OKLAHOMA 1983 Cold Case Solved — The Killer Was A Guest At Her Wedding
OKLAHOMA 1983 Cold Case Solved — The Killer Was A Guest At Her Wedding

There is a photograph. It was taken on Saturday, March 7th, 1981 on the steps of the First Methodist Church in Prairie View, Oklahoma. And it shows 23-year-old Karen Sue Wheeler in a white dress with a high lace collar, laughing, her new husband beside her in a rented tuxedo, and 140 guests fanned out on the steps behind them in their Sunday best.
Her mother had the photograph enlarged and hung it over the fireplace. It stayed there for 42 years. And for 42 years, every time Wanda Wheeler looked up from her chair, she was looking at the man who killed her daughter, standing in the fourth row, second from the left, in a brown suit, holding a paper cup of punch. He had signed the guest book.
He had eaten the cake. 3 months later, he had come to the door of the little house on Cottonwood Street while her husband was on a two-e hitch on a drilling rig and Karen had let him in because he had been at the wedding. But to understand how this ended, you have to know how it began. Prairie View sits in Redbud County in the red dirt plains of western Oklahoma where the wheat runs to the horizon in every direction and the pump jacks nod in the fields like slow patient animals.
In 1981, the population was 3,100 and the oil boom was at its peak. Every drilling company in the Anadarko Basson was hiring, and the men of Prairie View worked two weeks on and one week off, and came home with more money than the town had ever seen. There was a courthouse square, a Sonic, a co-op elevator, a Methodist church and a Baptist one, and a Dairy Queen where the Rough Necks ate.
At 3:00 in the morning, men drove new Ford pickups and listened to Merl Haggard and the Sooners. Kids rode bikes on section roads and swam in stock tanks. In June, the wheat harvest ran around the clock, and the combine’s lights moved across the fields all night, and the air smelled like cut wheat and crude oil and dust. Nobody in Prairie View locked a door.
The rough necks were gone half the time anyway, and their wives kept each other company on the porches and listened to the combines run all night. Karen Sue Wheeler was the younger of two daughters. Her father, Roy, farmed wheat and ran cattle. Her mother, Wanda, taught Sunday school and had made Karen’s wedding dress by hand.
Karen had gone to the junior college in Weatherford and had come home to work as the receptionist at the Redbud County Clinic, where she had a habit that every child in the county remembered. She kept a jar of lollipops on the counter and let each child pick one on the way in, not the way out, because she said they had already been brave enough to come.
She had married Brad Morgan on March 7. Brad was 25 and worked as a derkand for Anadarko Drilling. Two weeks on, one week off. They had rented a small house on Cottonwood Street and painted the kitchen yellow. Karen was going to nursing school in Weatherford in the fall. She had already bought the shoes, white ones, and they were in the box in the closet with the tissue paper still folded over them.
Brad’s crew on the rig was five men. One of them was Curtis Mbry. He was 27, a motorman, quiet, unmarried from a town 40 miles east. He had been at the wedding because Brad had invited the whole crew. He had signed the guest book Curtis M. He had danced once with Karen’s sister. He had told Brad the house on Cottonwood Street was a nice little place.
Prairie View would have told you Curtis Mabberry was a good hand who kept to himself. That was the last spring any of them believed it. In the wedding photograph, if you look closely, he is not looking at the camera. He is looking at the bride. On Monday, June 8th, 1981, Brad Morgan left for a twoe hitch on a rig near Elk City, 90 miles west.
Curtis Mabry was on the same crew on the same rig on Thursday, June 11. According to the rig’s tour sheets, Mabry left the location at 6 natto. On his off shift and did not return until 4:00 a.m. Friday, nobody thought anything of it. Motormen came and went. Elk City to Prairie View was 90 minutes on Highway 34, and Mabberry had made the drive a dozen times that spring because Brad had asked him to bring Karen a paycheck once, and he had kept offering.
On Thursday, June 11, Karen worked at the clinic until 5:00 p.m. At 5:30, she stopped at the IgA and bought a chicken and a jar of lollipops. At 600, she called her mother and said she was going to fry the chicken and watch television. At 7:15, Wanda called back to ask about Sunday dinner, and Karen said yes and that the harvest crews were loud on the section road.
At 8:40, a neighbor named Ruby Toiver watering her tomatoes saw a blue pickup she did not recognize parked in front of the yellow kitchen house. and a man in a ball cap on the porch. She saw Karen open the door and step back to let him in. Ruby thought it was someone from the rig bringing word from Brad. At 9:30, the blue pickup was gone.
Ruby Toiver went inside to watch the news and would spend 42 years wishing she had walked across the street with a plate of tomatoes. At 7:00 Friday morning, Wanda called to remind Karen about the chicken bones for the dog. No answer. At 7:30, she called the clinic. Karen had not come in. At 80, Roy drove to Cottonwood Street.
The front door was closed. The kitchen light was on. The chicken was on the counter, halfeaten. The jar of lollipops was open. Karen was in the bedroom. The Redbud County Coroner ruled the death a homicide. She had been strangled. She had fought. On the hem of her night gown, the Osby Lab in Oklahoma City found blood.
Group B Karen was O. The night gown was sealed in a paper bag and placed in a box labeled 810612. The case went to Detective Hoy Reedenor, 47, of the Redbud County Sheriff’s Office, who had picked up a lollipop at the clinic counter for his grandson two weeks before. He would later say he could not take the boy back for a year.
The first suspect was the husband. It always is. Brad Morgan had been on the rig floor at Elk City with four men and a tool pusher from 6 o’clock p.m. Thursday until 6:00 am Friday, and the tour sheets showed it. That took a day. Brad drove home and sat in the yellow kitchen and did not speak for a week. The second suspect was a harvest hand.
A man named Dwight Puit, 31, on a custom cutting crew from Texas, had been at the Dairy Queen Thursday night and had a record for assault in Amarillo. Reedor found him in the crew’s bunk house on June 15 and questioned him for 9 hours. Puit had been running a combine on the Kesler place from
700 p.m. until 2 soak a.m. under lights, and the farmer and three men had watched him do it. He was cleared by June 19. And then there was the crew. Reinor asked Anadarko drilling for the tour sheets for June 11. They showed a motorman off location from 6:00 p.m. to 4:00 a.m. Reed interviewed Curtis Mabberry on June 22. Mabberry said he had driven to his mother’s in Clinton for supper and stayed late.
His mother said he had been there. Reedor noted on page 31 that Mabry drove a blue 1978 Ford pickup and that he had a healing scratch. Right hand states from a chain on the rig floor. He asked Mabber’s blood type. Mabri said he did not know. Reedor asked for a sample. Anadarko drilling. Superintendent who did not want Osby on his rig during the biggest boom in the basin’s history called the sheriff that afternoon and said the crew had been cleared by the tour sheets. And that was that.
The sheriff, whose brother sold pipe to Anadarko, told the Elk City paper in July that Karen had likely been the victim of a stranger following the harvest. While the sheriff’s office chased custom cutters across three states, the Wheelers tried to live. Roy cut his wheat because it did not wait.
Wanda hung the wedding photograph over the fireplace. Brad Morgan quit the rig, moved into the Wheeler’s spare room, and could not go back to the yellow kitchen. And every night, Wanda looked up from her chair at the 140 faces on the church steps. Then the years came. By 1983, the oil boom had crashed and half the men in Prairie View were out of work.
Curtis Mabry went to work for a pipeline company in Texas. In 1985, Brad Morgan remarried with Wanda’s blessing, and she made the bride a quilt. By 1991, 10 years had passed. 10 years. Wanda said the words at the supper table on the anniversary, and Roy got up and went out to the barn. Every June 11, the family and Brad drove to Cottonwood Street and left a jar of lollipops on the porch of the yellow kitchen house.
Hit Reedenor retired in 1997 and took a copy of the file, all 270 pages, home in a box that lived in his storm cellar. He read it every June, and every June he stopped on page 31 and thought about the superintendent’s phone call. The Sonic closed in 2005. The pump jacks in the fields stopped nodding one by one and then started again when the price came back.
The clinic moved to a new building in 2009 and the receptionist who came after Karen and the one after her kept the lollipop jar. Roy died in 2011. Wanda Wheeler was the one who never let go. She kept the photograph over the fireplace, and every June she wrote to the Osby asking whether the night gown from box 810612 had been tested with anything new.
In 2002, she was told the stain was degraded. In 2012, the same. She was 89. In 2023, she still looked up at the fourth row without knowing why.

Now, let’s get back to Karen. The case had been cold for 41 years when an Osby agent who was born in 1987 opened box 81 0612. Her name was Special Agent Tara Blackfox. And in 2022, the Oklahoma State Bureau of Investigation gave its cold case unit money for a new kind of testing. She read the Wheeler file in a weekend and then she drove to Prairie View and sat in her car outside the yellow kitchen house which had been painted white by someone who did not know.
She noticed page 31. She noticed the tour sheets. She noticed that the sheriff’s brother sold pipe. She wrote the name on a legal pad and underlined it. She sent the night gown to a private laboratory in Texas that specializes in recovering Dena from old degraded stains. In January 2023, the lab reported a full male profile, no match in the national criminal database.
So, the lab used forensic genetic genealogy, a method that uploads the unknown dina to public ancestry websites, the same sites ordinary people used to trace their family trees, and works backward from distant cousins through birth and aotment records until the branches narrow to one man. On Tuesday, March 21st, 2023, at 8:15 in the morning, Tara Blackfox opened the genealogologist’s report at her desk in Oklahoma City.
The profile belonged to a man descended from the Mabberry family of Kuster County, Oklahoma. Three brothers, two were dead. The third was born in 1954, had worked as a motorman for Anadarko Drilling in 1981, and appeared on page 31. She looked at the legal pad. She looked at the report. Then she asked the Wheeler’s daughter, Karen’s sister, Donna, for a copy of the wedding photograph and the guest book.
on the fourth row, second from the left. There he was. In the book in blue ink, Curtis M. She drove to Wanda Wheeler’s house that afternoon. She did not say the name. She said there was a match and that it was someone who had been in the file since 1981 and that he had been at the wedding. Wanda, 89, looked up at the photograph over the fireplace.
She asked one question. Which row? Blackfox told her. Wanda looked for a long time. Then she said, “I’ve been looking at him for 42 years.” Curtis Mabry was 69 in 2023. He lived in a trailer outside Clinton, retired from the pipeline, unmarried, a regular at the Wednesday senior lunch at the Baptist church.
He had never been arrested. In hindsight, there had been signs, the blue pickup, the scratch, and a note on page 44 from Brad Morgan himself taken in 1981, saying that Curtis had asked him twice on the rig in May whether Karen was scared of being alone out there, and that Brad had said no. She was tough. Reedure had underlined it.
Blackf Fox needed a confirming sample. On April 5, an agent sat at the Wednesday senior lunch in Clinton. And when Mabberry finished his plate and dropped his fork and cup in the bin, collected them. On April 28th, 2023, the lab confirmed it. The blood on the hem of Karen Wheeler’s night gown belonged to Curtis Mabry.
Blackf Fox drove to Brad Morgan first. He was 67, a grandfather, and he had worked beside Curtis Mabry for two years. He asked to be there. On the morning of Thursday, May 11th, 2023, at 7:20 a.m., Curtis Mabberry was on the step of his trailer with coffee when three unmarked cars pulled into the lot. Brad Morgan got out of the second one.
Tara Blackfox read the warrant. Mabberry set down his cup. He looked at Brad. According to the arrest report, he said, “I told you it was a nice little house. Brad said, “You did.” Prairie view did not know how to hold it. The Methodist church, whose steps were in the photograph, filled on Sunday. Ruby Toiver, 91, told the Elk City paper that she had told Reedenor about the blue pickup in 1981 and had been told it was probably a harvest hand.
Then the grief turned. People remembered the tour sheets. They remembered the superintendent’s phone call. They looked at their own wedding photographs. Court documents show that in September 2023, faced with the Dena and Brad Morgan’s statement, Mabry pleaded guilty to first-degree murder.
On October 13th, 2023, he was sentenced to life without parole. He was 69. Wanda Wheeler, 89, was wheeled to the podium by Donna and said that she had made her daughter’s dress by hand and that she had hung the picture over the fireplace so she could see her everyday and that she had seen him everyday, too. Maver stared at the table.
Hit Riddenor, 89, sat in the second row with the box from his storm cellar. Brad Morgan sat beside him. Karen Sue Wheeler was 23 years old. She let children pick a lollipop on the way in because they had already been brave and she had painted a kitchen yellow and bought her nursing school shoes. She had been married for 96 days and had a whole life in front of her that belonged to her by right and it was taken by a man who had signed her guest book.
After the sentencing, Wanda had Donna take the photograph down from over the fireplace for the first time in 42 years. They cut the fourth row off with scissors. Then they hung it back up. Wanda told reporters, “I’m not taking her down. I just took him out.” The Wheeler case was the first solved by Osby’s cold case unit, and every Red Bud County file from the boom years is now being reviewed.
The years have a way of burying things, but they do not destroy them. A stain on a hem, a tour sheet with an 8-hour hole, a face in the fourth row of a photograph over a fireplace. These things wait. The truth is patient in a way that people are not. What seemed settled in Prairie View in 1981 was never truly closed.
It was only waiting for someone to ask which row. So, we want to hear from you. Is life without parole at 69 justice, or did Curtis Mabri get 42 years he never deserved? What detail in this case stays with you most? The guest book, the tour sheets, or the photograph? And how many other wedding photographs are hanging over fireplaces right now with a face in them nobody has looked at twice? Justice came for Karen Sue Wheeler after 42 years.
Stories like hers remind us that truth, however late, always finds its way to the light. If you believe that, too, subscribe so you don’t miss the next case. And if you want more solved cold cases, the links are waiting in the description. Thank you for watching.
