In the early summer of 1988, twelve-year-old Doreen Jane Vincent was navigating a difficult transition. She had recently moved from the familiar surroundings of Bridgeport to a more rural home on Whirlwind Hill Road in Wallingford, Connecticut, with her father, Mark Vincent, and his wife, Sharon. Having been there for only about two weeks, Doreen was reportedly unhappy with the move, feeling isolated and missing her friends. This unhappiness was a backdrop to the events of June 15, 1988, the last day she was ever seen. On that evening, by her father's account, a volatile argument erupted between them. Mark Vincent later admitted to police that he had a temper and that on that day, he had become angry, hit Doreen, and pushed her into a window, causing it to break. Following this confrontation, he claimed she packed some clothes, took about fifty dollars in cash, and left the house between 8:00 and 9:00 p.m., presumably to hitchhike back to Bridgeport.
The initial hours and days following Doreen’s disappearance were marked by a concerning lack of urgency from her father. Mark Vincent did not notify the police or Doreen’s mother, Donna Lee, that the young girl was gone. It was not until three days later, on June 18, when Donna arrived at the Wallingford home to pick up her daughter for a planned visit, that she learned Doreen was missing. Mark allegedly seemed unconcerned, suggesting he believed Doreen had run away to her mother's home, as she had done on one previous occasion. It was only at Donna's insistence that a missing person report was finally filed with the Wallingford Police Department. Based on the history of her having run away before and her father's story, authorities initially treated Doreen's case as that of a runaway, a classification that may have critically delayed the investigation as the evidence trail grew cold.
As the investigation progressed, the runaway theory began to crumble under the weight of inconsistencies and suspicious circumstances. Doreen’s stepmother, Sharon, contradicted her husband's account, telling police that the front door had a deadbolt that required a key to open from the inside, making it unlikely Doreen could have simply walked out as he claimed. Detectives grew troubled by Mark Vincent's apparent lack of concern and the conflicting stories. A year after the disappearance, a search of the home of Doreen’s paternal grandmother in Bethel uncovered personal items and clothing that Mark had claimed his daughter took with her when she left. Though he has never been officially named a suspect, law enforcement has long considered his account of that night to be suspect. Over the decades, searches have been conducted with cadaver dogs in areas like Huntington State Park after a witness reported seeing a man who looked like Mark carrying a large, rolled-up, carpet-like object around the time Doreen vanished, but no trace of her has ever been found. The case of Doreen Vincent remains an open and haunting cold case, a transition from a runaway investigation to one where foul play is strongly suspected. Her family, particularly her mother, has been left without answers, holding onto the memory of a vibrant young girl who disappeared one summer evening.
