Warren Hart, a native Baltimorean who is now 42 years old, said he is telling his story publicly to show support for a man he has never met, Dontee Stokes.
"I came here to help Dontee," said Hart, who spoke tearfully to the press yesterday afternoon at the office of his lawyer, Joanne L. Suder. "When I heard what happened, I called up Joanne and said, 'This kid is not lying. I can see why he did it.'"
Stokes, 27, is charged with attempted murder and is being held on house arrest.
Blackwell, 56, is being investigated by the state's attorney's office but has not been charged with a crime.
Hart, who served in the Air Force after he left Baltimore, is scheduled to speak with detectives for the first time today about Blackwell.
Another alleged victim of Blackwell is also scheduled to speak with authorities today, according to Suder, bringing the total to five men who have accused the priest of abusing them when they were young.
"It was always known Maurice was with boys," said Hart, who grew up in the Gwynn Oak neighborhood in Northwest Baltimore.
Neither Blackwell nor his lawyer could be reached for comment yesterday.
Suder, who previously represented Stokes, declined to release Hart's last name until this afternoon. His identity was confirmed by law enforcement officials yesterday.
Warren A. Brown, Stokes' lawyer, said Hart's story makes Blackwell "more of a villain."
"It underscores even more the nature of Blackwell's relationship with these boys, that he was truly a sexual predator," Brown said. "When you treat people on a regular basis the way he treated Dontee and Warren, bad things are going to happen to you."
Hart said the alleged abuse lasted for at least two years, beginning in 1975 when he was 15 years old.
"There is no question people in the church knew or could have known," Suder said.
A spokesman for the Baltimore Archdiocese said it knew nothing about the alleged abuse in the 1970s. Hart is scheduled to meet with archdiocesan officials this week.
Hart is a computer network specialist who lives in Pembroke Pines, Fla., and has four children.
Looking back, Hart expressed conflicting feelings about Blackwell. Hart said that it was wrong for Blackwell to repeatedly rape him. But the Florida man also said the priest provided structure in his life and was a father figure to him after his father left. Hart even named his first-born son Maurice, who is now 23 years old, after the priest.
At the time of the alleged abuse, Hart's parents were going through a divorce, and he would sleep at the rectory two to three nights a week because he often didn't want to go home, Hart said. He had his own room at the rectory, he continued, and when he was in bed, Blackwell would come into the room.
