On December 3, 1999, Kathy Mohn had planned to leave her home in the Gulph Mills section of Upper Merion Township and travel to Levittown, Bucks County to spend the weekend with a friend, as she had done most weekends since September of that year. She had almost cancelled meeting her friend, she had Christmas gifts to wrap, but he convinced her to come, and bring the gifts with her so that they could wrap them together. She never made it to her destination.
Kathy was married to Main Line dentist Thomas Mohn. It was an unhappy marriage and while they both still lived in the Gulph Mills home, they were estranged. Both were having affairs and her relationship with her Levittown friend was no secret.
Kathy's friend had never met nor spoken with her husband, but when she hadn't shown up or phoned by Sunday, December 5th, he called Thomas Mohn. He just wanted to make sure that Kathy was alright. Thomas Mohn then reported Kathy missing, telling the police that she had left their home on Friday evening at 9pm to go visit a friend but had never arrived.
Kathy's vehicle, a green Ford Explorer, was found on December 13th, abandoned in the KFC parking lot at Route 13 and Levittown Parkway in Tulleytown, across the street from the SEPTA station. A restaurant employee said that the SUV had been there since at least December 5th. Inside were Kathy's glasses, her prescription medicine and her purse, but no wallet. The gifts she was supposed to be bringing to her friend's house were not in the car. When Kathy's friend first saw the SUV, he immediately became suspicious. It was clean, spotless, inside and out. No cigarettes in the ashtray or ashes on the floor. Kathy never kept the vehicle clean. There was always cigarette ashes and debris strewn about. And she never had an air freshener, but police found seven. The driver's seat had been pushed almost all the way back to accomodate a much taller person than Kathy's petite 5'2".
A videotape taken at the Bristol exit of the PA Turnpike showed what police say is Kathy's car exiting at around 9:54am on December 4th. The tape shows a blond woman leaning against the passenger side window. The driver is obscured except for an arm. Police brought in a cadaver dog to check Kathy's car. The dog reacted to the passenger side, as if he had found a body.
Police believe that Kathy was already dead when her car was filmed at the Bristol exit. The air fresheners were most likely to mask the smell of the body. After disposing of Kathy's body, the car may have been left where it was found to throw suspicion on Kathy's friend. Whoever killed her likely took the train to return home after abandoning the car.
Kathy's friend was eliminated from the list of suspects. Her husband was not. During a search of the Gulph Mills property, police found blood-like stains on a wall in the house. Soiled clothing and a dirty shovel were found in an outdoor shed. Kathy had consulted an attorney about a divorce and expected that she would be entitled to more than half of her husband's dental practice plus sizable support payments. And Kathy's husband stopped cooperating with the police.
Kathy's body has never been found and no one has been arrested for her murder.
