Lifetime is moving forward with plans to turn the story of the alleged “Craigslist Killer” into a TV movie.

Philip Markoff, who was given that moniker after being accused of killing a woman he met through Craigslist, committed suicide on Aug. 15 in a Boston jail cell while awaiting trial.

The movie, which went into development long before Markoff’s suicide, centers on the former Boston U. student who appeared to live a double life.

Markoff was in medical school and engaged to be married when he was arrested in the shooting of Julissa Brisman, and accused of robbing a Las Vegas woman and attacking a stripper.

Prosecutors said Markoff met the women by answering ads for erotic services on the Craigslist website.

Scribes Donald Martin and Stephen Tolkin are adapting the ripped-from-the-headlines story, which is set to be produced by Sony Pictures TV. Judith Verno is exec producer, while Stephen Kay will direct.

Martin is no stranger to adapting real-life crime tales, having penned “The Hunt for the BTK Killer” (which Kay also directed) and “Amber Frey: Witness for the Prosecution.”

Tolkin’s credits include “Summerland” and “Kate Brasher.”

Markoff killed himself a year and a day after he was supposed to be married in 2009.
