He used the make-shift blade to slash major arteries in his ankles, legs and neck, including the carotid artery in his neck, Conley said. Markoff's grisly suicide preparations included scraping a prison issue pen and a piece of metal into what Conley called a "primitive scalpel." Sources told ABC News the metal came from a metal plate Markoff pried off of an electrical outlet. "I think many people would say thank God I got away and never give it another thought, while others would get dragged into it," Dietz said. "It depends on how vulnerable to manipulation she is." Park Dietz of Newport Beach, Calif., told ABC News.

"It really depends on whether they can be successfully manipulated into taking responsibility for someone else's behavior," forensic psychiatrist Dr. Markoff's suicide and gruesome farewell to McAllister could affect his former fiancee, one expert said. McAllister could not be reached for comment, and has not issued a statement since her former boyfriend died. "We're still studying that," Conley said. Suffolk County District Daniel Conley confirmed the words above Markoff's cell door at a news conference today, but could not explain Markoff's use of the word "pocket." ABC News has learned that it was written above his doorway where he could see it, but correction officers could not easily see it. As previously reported, Markoff had written "Megan" and "pocket" in his blood on the wall. Photos of McAllister covered the small table in Markoff's cell. The murder suspect took elaborate steps to make sure he died, but he also made final homage to McAllister. Markoff's first attempted suicide occurred shortly after when he tried to slash his wrists with a serrated spoon. In the days immediately after his arrest, McAllister staunchly defended Markoff's innocence, but a few days later went to the jail where he was held and broke off their engagement.

When he was arrested in April 2009 he was engaged to marry fellow medical student Megan McAllister. Markoff, 24, killed himself on Sunday, the anniversary of what would have been his wedding day.
