She Was Carrying a Lifeless Baby While Eating A Happy Meal | Marissa Tietsort Case

On a freezing October night in central Wisconsin, a young mother picked up her infant son from a trusted babysitter. Hours later, investigators uncovered a horror story of systemic breakdown, deceptive calm, and an unthinkable crime.

Chapter I: The Cold Laundromat on Third Avenue

The cold in Wausau, Wisconsin, arrives early in the autumn, cutting through the streets by mid-October with a damp, unrelenting chill. By 9:00 p.m. on October 18, 2018, the small industrial town in Marathon County had settled into its nighttime quiet.

Inside a brightly lit laundromat at the corner of Third Avenue and Union Street, the low hum of heavy-duty tumble dryers offered warmth against the freezing air outside. Two sisters, Heather Gardner and Jessie, had stopped in to finish chores after a long day. Accompanying them were Heather’s two young sons: Jathan, a lively two-year-old toddler, and Benson, an 11-week-old infant nestled quietly in his infant car seat.

To any outside observer, it was an unremarkable Thursday evening routine—a hardworking young mother managing the endless demands of single parenthood with the help of family. Jessie held toddler Jathan on her hip, swinging him gently to keep him entertained while Heather sorted clothes across one of the large steel folding tables.

Baby Benson lay still in his car seat, his small winter hat pulled down low over his forehead, blanket tucked up near his chin. Heather had pulled up the rim of his hat when she placed him in the car earlier, wanting to make sure he wouldn’t wake up disoriented in the dark. He seemed to be sleeping deeply, undisturbed by the clatter of coins or the whirring machinery.

Then, Jessie paused. She set down a folded garment and leaned over the plastic car seat to check on her nephew.

What she saw stopped her breath.

Benson’s face was unnatural, drained of color to an eerie, ghostly shade. His lips were deep blue and strangely rigid—pressed tight as though sealed shut. Panicked, Jessie called out to Heather.

Heather rushed over, her heart plummeting as her hands touched her infant son. Benson was freezing cold to the touch. Desperate, Heather pulled the baby from his car seat, lay his tiny body onto the laminate folding table, and began administering CPR. Her hands pressed repeatedly against his small chest as Jessie frantically dialed 911.

Marquette County 911: “911, where is your emergency?”

Jessie: “Please, please! I’m at the laundromat on the corner of Third and Union… 923 Third Avenue. I have another child in my arms… MY SISTER’S BABY IS DEAD! We just picked him up from the babysitter’s!”

911 Operator: “Do you have him on his back? Okay, I need you to tip his head back…”

Jessie: “He’s freezing cold! He’s freezing cold!”

911 Operator: “I need you to blow into his mouth…”

When emergency personnel arrived moments later, the scene inside the laundromat was chaotic and heartbreaking. Paramedics and police officers immediately stepped in to relieve Heather, attempting advanced life support measures. But as first responders attempted to clear the infant’s airway to insert an oxygen tube, they encountered a terrifying physical barrier: the child’s jaw was completely locked shut.

His limbs did not drop flat against the hard surface of the table; instead, his small legs remained bent at rigid angles, frozen in the exact seated posture of the car seat he had been placed in hours earlier.

Rigor mortis—the post-mortem stiffening of muscle tissue that typically takes two to six hours to develop—had already fully taken hold.

First responders delivered the devastating news to Heather on the floor of the laundromat: her 11-week-old baby had been dead for hours.

Heather stared in absolute disbelief. She had only picked Benson up from his babysitter, 32-year-old Marissa Tietsort, less than an hour before.

How could a baby handed over by his caregiver, dressed in his winter clothes and buckled into his car seat, have been dead for hours? The answer lay on Lilac Lane, behind the front door of a home that state authorities had already been warned about.

Chapter II: The Illusion of Care

To understand the tragedy of October 18, 2018, one must trace the path of Marissa Tietsort—a woman whose outward image as a nurturing home caregiver starkly contradicted a documented history of severe child welfare interventions.

Marissa Tietsort was a 32-year-old mother living in Wausau with her long-term boyfriend, Adam. To neighbors, acquaintances, and desperate parents looking for affordable local childcare, she presented herself as a warm, maternal figure deeply devoted to children. In written correspondence and letters to pen pals, she frequently reiterated this self-crafted persona:

“I love kids so much. Kids are everything to me. I love being a mom.”

Behind this polished facade lay an alarming institutional record. By late 2018, Marissa had given birth to five children. However, Wisconsin Child Protective Services (CPS) and the family court system had already permanently terminated her parental rights to four of those children.

In family welfare jurisprudence, termination of parental rights represents the absolute last resort. Unlike temporary foster placements or court-ordered rehabilitation plans—where states actively work toward family reunification through supervised visits and mandatory counseling—a permanent termination signifies that a court found severe, irremediable risk to the safety and well-being of the children.

Marissa’s four eldest children had been removed from her care entirely, legally freed for adoption by other families.

Yet, by 2018, Marissa was living in Marathon County, pregnant with her sixth child, caring for her fifth child (an infant boy), and quietly operating an informal, unlicensed childcare service out of her rental home on Lilac Lane.

In the gig economy of working-class communities, unlicensed home daycares often fill a critical gap. Licensed child care facilities in Wisconsin can cost upward of thousands of dollars a month per child, requiring long waiting lists that hourly shift workers cannot afford. Informal arrangements—where a local mother watches neighborhood children for a modest cash fee—are common.

For parents like Heather Gardner, finding Marissa felt like a stroke of luck grounded in familiar history.

Heather was a 26-year-old single mother striving to build a stable life for her two young sons. Working as a medical billing coordinator, her income covered basic living expenses but left no room for expensive commercial daycare facilities. Having lost her own mother a few years prior, Heather lacked a familial support net to assist with daily childcare.

Heather and Marissa had known each other casually since high school. Years later, they reconnected through Marissa’s sister, who was a close friend and coworker of Heather’s. When Heather expressed her urgent need for affordable childcare during her work shifts, the recommendation came naturally.

“Marissa just had a newborn, so she’s home all day,” Heather was told. “She’s great with kids, and she won’t charge much.”

Because the arrangement was rooted in high school familiarity and endorsed by a trusted friend, Heather felt a sense of security. Marissa was not a stranger found on an anonymous online board; she was a mother known to her inner circle.

Heather began dropping off two-year-old Jathan and infant Benson at the Lilac Lane residence whenever her work schedule demanded it. For months, the arrangement seemed to function smoothly.

What Heather did not know—what the broader public was entirely unaware of—was that state law enforcement had already intervened at that very address just weeks before.

Chapter III: Unheeded Warnings

Two months before Benson Gardner entered Marissa Tietsort’s home, Detective Jennifer Holtz of the Marathon County Sheriff’s Office had opened an active investigation into Tietsort regarding an incident involving another infant.

In August 2018, emergency medical personnel were dispatched following reports that an infant in Tietsort’s care had suffered severe facial and head injuries. Upon medical evaluation, physicians discovered the child had sustained a fractured skull and a potential brain hemorrhage—injuries that medical experts noted were entirely inconsistent with a minor tumble.

When Detective Holtz inspected the Lilac Lane home, she was met with immediate resistance. Marissa’s boyfriend, Adam, answered the door, offering a convoluted explanation for the infant’s condition. He claimed the baby had simply rolled off a low living room couch and struck a coffee table while Marissa was in the adjacent bathroom.

During police questioning, Adam became visibly defensive, attempting to deflect suspicion:

Adam: “Whenever she babysits kids, we have this coffee table in the living room where the kids can put toys… She was over here sleeping, and Marissa just went to the bathroom. She was pulling her pants up when she heard her crying… People need to come talk to us before getting you guys involved.”

When Detective Holtz requested to interview Marissa directly, the caregiver’s demeanor stood out as unnerving. According to investigative reports, Marissa walked past the lead detective without making eye contact, offering no greeting, and showing no emotional distress regarding the critical condition of an infant left in her charge.

When pressed, Marissa maintained her flat narrative: she was washing dishes, the child rolled off the couch, and the injuries were a unfortunate accident.

The medical assessment indicated blunt force trauma rather than an accidental fall. Social services stepped in swiftly regarding Marissa’s own fifth child who was residing in the home. Because Marissa had already lost her parental rights to four children due to prior state action, social services informed the couple that her fifth child would need to be placed immediately with an approved relative pending further investigation.

Upon hearing that child welfare officers were taking custody of his child, Adam lost control. He grabbed the crying baby boy, screamed at the responding officers, and threatened violence:

Adam: “If you think you’re going to do anything with my kid, you better bring the SWAT team! That’s exactly what I said, and I’m sticking to it! You guys need to leave!”

Throughout the explosive confrontation, Marissa stood quietly to the side, completely unbothered. She casually offered to step outside the residence so that Adam could retain the infant inside.

Ultimately, law enforcement managed to de-escalate the situation and process the immediate child safety orders. Before departing, authorities issued an explicit directive to Marissa Tietsort: she was barred from having any unsupervised contact with children until the criminal and civil investigations were formally concluded.

However, in the absence of continuous physical monitoring, electronic tagging, or daily welfare checks, the order relied entirely on voluntary compliance. The state issued a prohibition, but the system left the door on Lilac Lane unlocked.

Marissa Tietsort continued to take in neighborhood children for cash. And two months later, on October 18, 2018, Heather Gardner pulled into her driveway.

Chapter IV: The October 18 Shift

Thursday, October 18, began like any ordinary workday for Heather Gardner. Before bringing her sons to Lilac Lane, she took meticulous care to prepare them for the evening. She fed 11-week-old Benson, dressed two-year-old Jathan in warm autumn clothing, and gathered their diaper bags, bottles, and extra blankets.

At approximately 4:00 p.m., Heather and her sister Jessie arrived at Marissa’s home. The sun was beginning to dip, casting long shadows across the quiet residential street.

Heather carried Benson up the front steps while Jessie walked alongside Jathan. Marissa answered the door wearing plain domestic clothes—jeans and a t-shirt, her hair pulled back into a simple tie.

“He just ate, so he might be a little fussy,” Heather noted as she handed Benson over. “I’ll probably be back to pick them up around 7:30 or 8:00.”

“I’ve got him,” Marissa responded with a calm smile.

Before stepping back toward her car, Heather leaned down, kissed baby Benson gently on his forehead, and held his small face for a brief moment—a routine, loving gesture shared between a mother and her child every day.

“See you soon, baby,” Heather said.

It was the last time Heather would ever see her son alive.

Chapter V: The Hand-Off in the Dark

By the time Heather and Jessie returned to Lilac Lane to pick up the boys, it was shortly after 8:00 p.m. The October night had turned bitterly cold, blanketed in total darkness.

Heather stepped out of her vehicle and walked up the paved walkway to the front door, expecting the usual pickup routine. Over the preceding months, collecting the children was always a extended process: Heather would step inside the house, help put on the boys’ jackets, gather scattered bottles and toys, and secure Benson into his car seat inside the warmth of the living room.

Tonight, however, the routine was abruptly shattered.

Before Heather could even ring the bell, the front door swung open. Marissa stood directly in the doorway, holding two-year-old Jathan with one hand and carrying Benson—already fully buckled into his infant car seat—in the other.

She was waiting at the threshold like someone counting down the seconds to an eviction.

Both Heather and Jessie immediately sensed that something was terribly amiss. Marissa appeared visibly disheveled. Her face was bright red, she was sweating noticeably despite the freezing outdoor temperature, and her movements were rushed and erratic.

As Heather took the car seat, she noticed a prominent red mark on Marissa’s neck. When Heather asked about it, Marissa offered a brief, nervous laugh, brushed the question aside, and hastily handed over the toddler.

Without engaging in any further conversation, Marissa pulled the door shut, locking it from the inside before Heather had even turned back toward her vehicle.

Standing on the porch in the freezing wind, Heather looked at her sister in confusion. “Jesus Christ, what was that?” she remarked. The interaction was jarringly abrupt, but Heather assumed the babysitter was simply overwhelmed or stressed.

Heather glanced down into the car seat. Benson appeared to be sleeping soundly. He was dressed in his bulky winter snowsuit, and his small knit hat was pulled low over his face, partially covering his eyes.

Desiring not to wake an infant who had finally settled to sleep, Heather gently adjusted the rim of his hat slightly, secured the car seat into the back base of her vehicle, and drove toward the laundromat on Third Avenue to complete her evening errands.

She had no way of knowing that the infant resting in the back seat was no longer alive—and had not been for hours.

Chapter VI: The Midnight Manhunt

The frantic 911 dispatch from the Third Avenue laundromat transformed the quiet night into an all-out homicide investigation.

While paramedics worked uselessly over Benson’s body on the folding table, Detective Jennifer Holtz arrived at the scene. As soon as Heather Gardner and her sister Jessie gasped through their tears that they had just picked up the baby from their babysitter, Detective Holtz recognized the name immediately: Marissa Tietsort.

The history came flooding back—the August skull fracture incident, the uncooperative home visit, the court mandate prohibiting contact with children.

While investigators preserved the laundromat as a crime scene, a wave of anger and panic swept through the family. In the chaotic aftermath of learning her nephew was dead, Jessie picked up Heather’s cell phone and fired off a direct text message to Marissa:

“You killed my sister’s baby.”

Moments later, realization set in that sending the message might alert the suspect. The warning shot had been fired.

By 1:00 a.m., patrol units and detectives from the Wausau Police Department and Marathon County Sheriff’s Office descended upon the residence on Lilac Lane. Officers surrounded the property, knocked forcefully on the doors, and announced their presence:

Officers: “Marissa Tietsort! We have a warrant! Come out! We are not going away!”

There was no response. The windows remained dark, and the property stood completely silent.

Exercising an emergency search warrant, law enforcement breached the front door and cleared the premises room by room. The apartment was completely abandoned. The beds were unmade, toys lay scattered across the living room carpet, but neither Marissa, her boyfriend Adam, nor her remaining child were inside.

Detective Holtz immediately initiated emergency tracking protocols through Marissa’s mobile service provider. Cell tower ping data quickly narrowed down the phone’s physical location to a commercial corridor a short distance away: The Plaza Hotel, a local lodging facility.

At approximately 4:00 a.m. on October 19—seven hours after Benson was pronounced dead—detectives accompanied by uniformed officers quietly moved down the carpeted hallway of the hotel, stopping outside Room 114.

Detective Holtz knocked firmly on the door.

After a brief delay, the door opened slightly. Adam stood in the doorway in his nightclothes, looking bleary-eyed and bewildered.

Detective Holtz: “Morning, Adam.”

Adam: “What are you guys doing?”

Detective Holtz: “Is Marissa here? Adam, just cooperate with us, okay? We’ll explain everything in a second.”

Adam: “Well, you already charged her, right? You guys are harassing the hell out of us. If she already got charged, why do you got to come here?”

Detective Holtz: “Because we need to talk to her about something new.”

Behind Adam, inside the dimly lit hotel room, Marissa was sitting up in bed. Her reaction to the pre-dawn police raid was remarkably flat. There was no terror, no confusion, no frantic demand to know what had occurred.

Instead, she offered a casual, almost annoyed query:

Marissa: “Why are you guys here? We wanted to get away… Isn’t it against the law to come stay at a hotel room for the night?”

Officers placed both Marissa Tietsort and Adam into custody, securing them in separate police cruisers for transport to the Wausau Police Department for formal interrogation.

Chapter VII: The Interrogation and the McDonald’s Trip

Inside the stark interrogation rooms of the department, Detective Holtz and lead investigators began unraveling a timeline of events that defied basic human comprehension.

Sitting across from detectives, Marissa maintained an unnerving composure. She did not cry, nor did she inquire about the health or safety of baby Benson. She spoke in an even, measured tone, attempting to frame Thursday afternoon as a completely unremarkable day of childcare.

Detective: “Tell me about taking care of him today.”

Marissa: “Oh, I was just watching him, and he was fine… I fed him once. And then he slept. We went outside when they first got there a little bit.”

Detective: “Okay. And what did you guys do after that? After Adam got home?”

Marissa: “We went to eat a little bit after he got home… We went to McDonald’s.”

Detective: “Which one?”

Marissa: “The one over by the courthouse. We went inside… Ate inside for maybe 15 minutes tops.”

As detectives listened, the timeline Marissa presented began to trigger alarm bells.

According to Marissa, shortly after Adam returned home from work in the late afternoon, the couple decided to take all the children—including infant Benson—out for dinner at the local McDonald’s fast-food restaurant near the county courthouse.

She claimed that prior to leaving, she had dressed Benson in his heavy winter snowsuit and placed him into his car seat. She insisted that after returning home from McDonald’s, she simply left Benson inside his car seat in the living room because she anticipated Heather’s arrival shortly thereafter.

Detectives paused, staring intently at the suspect. They knew, based on the preliminary medical findings from the laundromat—the presence of advanced rigor mortis—that Benson had been dead long before Heather picked him up at 8:00 p.m.

Detective Holtz leaned forward, dropping the calm conversational tone.

Detective: “Marissa, the reason we’re here… do you know why?”

Marissa: “Why? Is he dead? I know.”

Detective: “We were hoping you could shed some light on that.”

Marissa: “I don’t know what happened.”

Detective: “Marissa, this is the most important conversation you’ll ever have in your life. I need you to tell me the truth. Heather deserves to know what happened.”

Even as the weight of a homicide investigation pressed down upon her, Marissa’s demeanor remained surprisingly flat. She repeatedly rubbed her nose and scrunched her face, mimicking the physical motions of crying, yet officers noted that not a single tear fell from her eyes.

Marissa: “I promise you, I would never kill a baby! I didn’t kill him!”

Detective: “Marissa, sometimes it’s not what you do—it’s what you don’t do. Maybe you left him alone for too long? Was it an accident?”

Marissa: “I left him in the Pack ‘n Play after we got back inside… He didn’t make any noise. I have that video monitor thing. I didn’t kill him, I promise.”

Under relentless questioning, Marissa’s narrative began to fracture into contradictory fragments.

She initially claimed she continuously monitored the baby via a video screen. Then, within minutes, she altered her story, admitting that she had actually found the infant unresponsive in his crib hours earlier—long before Adam arrived home, and long before the evening trip to McDonald’s.

Detective: “When did you realize he wasn’t breathing?”

Marissa: “I don’t know… I went in and he felt cold. And I was scared. My boyfriend wasn’t there… It was like 5:50 or 6:00 p.m.”

Detective: “Where was his face?”

Marissa: “Face down.”

Detective: “And what did you do when you found him cold at 5:50 p.m.?”

Marissa: “I didn’t tell Adam… I just left him.”

Detective: “You left him? And then did you go to McDonald’s?”

Marissa: “Yeah, we went to McDonald’s.”

The admission sent a shockwave through the interrogation room.

By her own verbal admission, after realizing that 11-week-old Benson was unresponsive and ice cold in his crib around 5:50 p.m., Marissa Tietsort did not call 911. She did not seek medical assistance. She did not notify the child’s mother.

Instead, she placed the deceased infant into his winter snowsuit, buckled his lifeless body into his car seat, covered his face with his winter hat, and rode with Adam and the other children to McDonald’s.

Security camera footage retrieved by investigators from the McDonald’s location confirmed the horror: Marissa Tietsort walked into the restaurant carrying the car seat containing deceased baby Benson, placed the car seat beside her booth, and sat down to eat a meal with her family while the infant lay dead beside her.

Following the meal, they returned to Lilac Lane. When Heather arrived at 8:00 p.m., Marissa handed over the car seat containing the dead child, closed her front door, and immediately packed her bags.

By 9:50 p.m., Marissa and Adam had checked into Room 114 at the Plaza Hotel.

When detectives questioned her regarding the absurd logic of checking into a local hotel less than two hours after handing a dead baby to his mother, Marissa offered a bizarre explanation: she had received a small insurance settlement from a previous car accident and wanted to use the hotel’s indoor hot tub to ease her back pain.

Detective: “Nobody who lives in this town checks into a hotel at 9:50 p.m. after a baby died in their apartment.”

Marissa: “I didn’t know he died!”

Detective: “That is a lie, because Jessie texted your phone telling you he died.”

Marissa: “My phone was off!”

Detective: “How do you think we found you here?”

Simultaneously, in a separate interrogation room, investigators briefed Adam on the situation. Unlike Marissa’s flat demeanor, Adam appeared genuinely stunned when officers informed him that Benson had been dead during their dinner outing.

Adam: “Dead?! Come on now… I swear to God I didn’t know! She didn’t tell me?!”

Security camera footage from the hotel and fast-food restaurant reinforced the conclusion that Adam had been kept entirely in the dark regarding the infant’s true physical condition throughout the evening. Marissa had used heavy clothing, blankets, and a low-drawn winter hat to stage the illusion of a sleeping child.

Chapter VIII: The Forensic Reality

While Marissa Tietsort attempted to portray Benson’s death as an accidental sudden infant demise or a case of simple monitoring oversight, forensic pathology delivered an undeniable, devastating verdict.

An autopsy was performed by the Milwaukee County Medical Examiner’s Office. The physical evidence completely shattered any remaining claims of accidental suffocation or sudden infant death syndrome (SIDS).

The medical examiner determined that Benson Gardner died from severe blunt force trauma to the head and abdomen.

The autopsy revealed:

• Significant internal cranial injuries consistent with direct, severe impacts.

• Severe blunt trauma to the torso resulting in internal injuries.

• A fractured tailbone—an injury requiring extraordinary, localized force that could only occur through severe physical assault.

The medical examiner officially ruled the death a homicide. Furthermore, forensic experts confirmed that the traumatic injuries were inflicted hours before Heather arrived to collect her children.

The medical data proved beyond a shadow of a doubt that Marissa Tietsort had violently assaulted the 11-week-old infant, inflicted lethal internal injuries, and then spent the subsequent four hours engaging in a calculated cover-up: staging the body, concealing the child’s face, carrying the deceased baby out in public to eat fast food, and finally handing the lifeless infant back to his unsuspecting mother in the dark.

Chapter IX: The Legal Reckoning

In January 2019, the Marathon County District Attorney’s Office formally filed criminal charges against Marissa Tietsort.

She was charged with First-Degree Intentional Homicide—the most severe criminal charge under Wisconsin state law, carrying a mandatory sentence of life imprisonment. In addition to the homicide charge stemming from Benson’s death, prosecutors stacked multiple felony counts of child abuse relating to the prior August 2018 incident involving the fractured skull of the other infant in her care.

The court set bail at $500,000 cash, reflecting both the severity of the charges and the flight risk demonstrated by her hotel check-in on the night of the crime. Unable to post bond, Tietsort remained incarcerated at the Marathon County Jail awaiting trial.

Throughout the pre-trial proceedings, the case generated immense local and national outrage. Media outlets focused heavily not only on the horrific nature of the crime, but on the profound administrative gaps in the social welfare system that permitted a woman with permanently terminated parental rights and an active child abuse investigation to continue operating an unlicensed home daycare.

Community advocacy groups called for stricter regulatory oversight of informal childcare providers and enhanced communication channels between law enforcement agencies and child protective services.

In 2020, facing a mountain of forensic evidence, security camera footage, and recorded interrogation admissions, Marissa Tietsort entered a plea agreement. She pleaded guilty to reduced charges of First-Degree Reckless Homicide and intentional child abuse.

During the sentencing hearing in Marathon County Circuit Court, the courtroom was filled with law enforcement personnel, community members, and Benson’s family.

Heather Gardner delivered a heartbreaking victim impact statement, confronting the woman she had once considered a friend:

“You took away my baby’s future. You took away his first steps, his first words, his entire life. You handed me my dead son in a car seat and walked away to a hotel like he meant nothing.”

The presiding judge delivered a scathing rebuke of Tietsort’s complete lack of empathy and calculated post-crime behavior, emphasizing the horror of carrying a deceased child into a public restaurant to eat a meal before handing him off to his mother.

Marissa Tietsort was sentenced to substantial state prison time followed by extended supervision, ensuring she would spend decades behind bars, removed entirely from society.

Chapter X: Legacy and Reflection

The story of baby Benson Gardner remains one of the most sobering cases in modern Wisconsin jurisprudence—a painful testament to how easily domestic violence can hide behind simple daily routines.

For working families across the country, the case highlighted the terrifying vulnerabilities inherent in informal childcare arrangements. It exposed the stark reality faced by single parents who are forced to balance the necessity of earning a living with the immense difficulty of securing safe, reliable, and affordable care for their children.

In Wausau, the corner of Third and Union no longer carries the frantic panic of that October night, but for those who lived through it—the paramedics, the detectives, and above all, the family—the memory remains sharp.

Heather Gardner’s loss sparked broader conversations across Wisconsin regarding child welfare reform, leading to calls for better integration between law enforcement records and child care oversight boards.

Yet for a mother whose world ended on a folding table in a cold laundromat, institutional reforms offer little comfort. The memory that lingers is not of courtrooms or investigative files, but of a small, ordinary moment on Lilac Lane at 4:00 p.m.—a mother leaning into a car seat, kissing her infant son’s forehead, and promising to see him soon.
