In June 1988, 12-year-old Doreen Vincent moved into her father Mark Vincent’s home on Whirlwind Hill Road in Wallingford, Connecticut. The rural setting was a stark contrast to the urban environment of Bridgeport, where she had previously lived with her mother, Donna Lee. Doreen was reportedly unhappy with the move and missed her friends, leading to frequent arguments with her father. Just ten days after relocating, Doreen vanished without a trace .
On the evening of June 15, 1988, Mark Vincent claimed that after an argument, Doreen took some money and clothes and left the house between 8:00 and 9:00 p.m. He stated he last saw her in the kitchen before going to his workshop. When he checked her bedroom at 9:00 p.m., she was gone. Sharon Vincent, Mark's wife, was at church during this time. Upon returning home at 11:30 p.m., Mark informed her of Doreen's absence. Notably, Mark did not report Doreen missing until June 18, after Donna Lee visited and insisted on involving the police .
Mark's account raised several concerns. Sharon noted that the front door had a deadbolt requiring a key from the inside, making it unlikely Doreen could have left that way. Additionally, Mark had removed the phone from the wall, preventing Donna from contacting the house. He also failed to inform his mother or Donna about Doreen's disappearance in the days following .
Initially treated as a runaway case due to a previous incident where Doreen had hitchhiked to her mother's home, the investigation's focus shifted as inconsistencies in Mark's story emerged. Items he claimed Doreen took were later found at his mother's house. A gun registered to Sharon was also discovered there, leading to Mark's conviction for illegal firearm possession .

on Vanished at Sea: The Mysterious Disappearance of Cameron Booth Off Chincoteague's Coast
He was a criminal, an abuser, likely who didn't want to face justice of his actions and took his own life because he could not face the consequences of what he did. The victims have told the family his crimes, with evidence. The family knows he was arrested and convicted of possession of CSAM. They know who and what he was. And they're all so equally sick they live in comfort that the victims don't want to retraumatize themselves over everything he put them through. Dont support this families sick parade of using a monster to get sympathy. He was never ashamed of who he was. He loudly boasted his crimes and justified them. The family shouldn't sit there and pretend, how far from reality are they to sit and post this man publicly on news outlets, websites, knowing who he is. Do they need attention that badly? They don't want the attention from the truth. The victims will never get justice. Do not pray for him o
