Mom Warned “Craigslist Killer” Suspect’s Fiance: There’s A Killer On The Loose

Megan McAllister’s mother warned her to be careful, that there was a killer on the loose.

Neither mom nor daughter, however, suspected that police believe the killer is Megan’s fiance.

The shocking detail of mom’s warning has been revealed in the course of the police investigation into Philip Markoff, 23, a Boston University medical student charged with murder and now known as the “Craigslist Killer.”

But to Megan he was simply a gentle soul, the man she was going to marry.

On Monday, McCallister and Markoff were watched by police as they left his Quincy, Mass. apartment building. After a while cops pulled them over on I-95.

They were taken to headquarters for questioning.

McCallister, according to mulitple reports, was nervous and full of questions as police spoke to her. When they broke the news that her fiance was suspected of murdering 26-year-old Julissa Brisman she cried.

During that session with police McCallister revealed she had not followed the case closely but that her mother had warned her to be careful because a killer was in the area.

And despite the evidence piling up against Markoff, McCallister has stood by him, sending an email to a news outlet saying that he couldn’t have done it and attesting to his character.

Meanwhile, police found a gun hidden in a hollowed copy of Gray’s Anatomy of the Human Body in Markoff’s apartment. They also found underpants that they believe are mementos from various attacks he allegedly committed.

The gun is being tested to see if it is the weapon used to murder Brisman, who was shot through the heart.

Brisman had placed a massage services ad on Craigslist and that’s how, police say, Markoff met her. They are establishing a pattern of Markoff meeting women that way and robbing them and believe he was doing it to feed a gambling habit.
