When Mary Florence Wiles Martinchuk was found dead in her Austinburg Township home in Ashtabula County, Ohio, on March 30, 2014, what followed was an extensive homicide investigation. There was no doubt that the 82-year-old had been heinously killed on the cold, fateful morning, owing to the evidence at the scene, as explored in ID’s ‘Interrogation Raw: Death at the Doorsteps.’ It did take authorities a few months, but they were ultimately able to give her justice with the help of genetic proof in the form of DNA as well as a delivery receipt from months prior.
Mary Martinchuk Was Fatally Attacked in Her Own Home
Born on October 28, 1931, in Painesville, Ohio, to Mary Schley and Rufus Wiles, Mary Florence Wiles Martinchuk was one of three children – her siblings were Rosie Wiles Kidwell and Carl Wiles. However, as the years passed and she grew into her own, the most important person in her life became a military man by the name of Fred Martinchuk, since they had fallen head over heels in love. The couple blissfully tied the knot on July 15, 1960, following which they settled in suburban Ashtabula County before welcoming a daughter, Anne Martinchuk Pfouts, into the world.

Mary and Fred built a good life for themselves in the city of Geneva, where he served as a bus driver, mechanic, and transportation supervisor, while she dedicated herself to the local community. They honestly led a good, stable life, raised a loving daughter, and eventually evolved into grandparents, but things changed on November 8, 2009, when Fred sadly passed away at age 76. His wife was heartbroken, but she still gradually managed to continue attending church weekly, baking for her senior community, and volunteering at local establishments whenever possible.
Mary was thus still pretty independent, but one of her neighbors took up the responsibility of clearing her driveway and getting her mail by the time 2014 rolled around, since she was over 82. Therefore, that’s precisely what Michael Kovac ik came to do on the late morning of March 30 after a bit of snowfall, only to grow worried when the grandmother of 2 didn’t respond to knocks. He looked into the window to see if everything was okay, but it wasn’t. Mary was lying in a pool of blood on her dining room floor with blunt force trauma to the head, and both her arms were nearly severed. Her pants were also pulled down, and her bent cane was lying nearby, making it clear she’d been fatally attacked.
Investigations Into Mary Martinchuk’s Homicide Centered Around DNA Evidence
It was shortly after 11 am when Michael Kovacik dialed 911 to report the possible homicide, also relaying to the dispatcher that he’d noticed footprints as well as tire tracks on the snow-covered ground. When investigators arrived at the scene, they didn’t take long to confirm the murder, the double tracks, as well as the fact that the weapon used in the fatal attack was most likely Mary’s own cane. They even uncovered through the meticulous health records the 82-year-old kept for herself that she had tested her blood sugar at 8:20 am, so the window for the crime was less than three hours.

Authorities thus came up with two hypotheses: a crime of passion due to the brutality inflicted or a home invasion gone wrong since Mary’s purse, television, and DVD player were also missing. Little did they know her purse would be found by a good Samaritan within hours and handed over to local police, only for it not to be connected to the active homicide case until April 7, 2014. The good Samaritan was subsequently questioned, just as neighbor Michael Kovacik, daughter Anne Martinchuk Pfouts, and anyone else close to the victim were, but no leads came of it. However, things changed on April 12, when forensic analysts informed detectives they were able to build a clear profile of their suspect from all the DNA evidence recovered from the scene.
We specify “all” because the same DNA underneath Mary’s nails – she had managed to scratch her assailant – was on the doorknob of her back door and on a cable from the missing television. What followed was an extensive analysis of DNA samples collected from anyone she could have had contact with in the days preceding her death, but to no avail. She also didn’t have a lover or any enemies who may have wanted to harm her in such a heinous manner, which left officials with no real leads. That’s when they decided to follow up on a delivery receipt they had initially found in her home – one from a store called Griffith’s Furniture dated July 2013 for her television and DVD player. They learned that two men delivered the items, and one of their DNA profiles perfectly matched the suspect’s, leading to the identification of Tommy Richter on November 13.

Once investigators zeroed in on Tommy, they discovered he was a 49-year-old recently divorced general laborer who was no longer employed at Griffith’s Furniture. It also came to light that they had briefly interviewed him months prior, when they first found the receipt, but nothing about him had stood out to them at the time. They hence began looking deeper into him, resulting in them uncovering that he was reportedly addicted to cocaine and had an alleged history of stealing to finance his habits. According to the aforementioned original, he had allegedly been reported for theft by at least an aunt as well as his ex-wife, yet he struggled to admit he had an issue. Unfortunately, this pattern continued during his interrogation on November 14, 2014.

While detectives laid out to Tommy that they had him for Mary’s homicide based on undeniable forensic evidence, he maintained he had never been to her home except for the delivery in 2013. He even claimed he had been clean for “several months” before vehemently asserting again and again that he had no hand in the crime. Nevertheless, he was arrested and detained on the charge of aggravated murder, driving him to reach out to officials on his own three days later, on November 16. That’s when he confessed, hesitantly detailing how he was high on the morning of March 30 and driving around in the area when he remembered the delivery he had made 8 months prior.
So, Tommy stated he drove to Mary’s place with the intention of quickly robbing the 82-year-old, but he somehow ended up knocking on her door. He claimed she let him inside, yet the civil mood between them shifted the moment he tried to steal, as she didn’t hesitate to defend herself. That’s when he lost his cool, he confessed, asserting he wasn’t himself and that it was the drugs acting on his behalf since he was high on cocaine. In the end, on June 3, 2015, he pleaded guilty to one count each of aggravated burglary and murder, for which he was sentenced to 15 years to life in prison plus 3 years. Therefore, today, at age 61, he is incarcerated at the mixed-security Allen Correctional Institution in Lima, Ohio, where he is expected to remain until he becomes eligible for parole in September 2032.
