Philip Markoff is a 22-year-old medical student who is engaged to be married but is best known for being accused of being the "Craigslist Killer" who murdered a pretty New York masseuse and attacked at least two other escorts in hotels.

Philip Markoff is a Boston University student. He lives in Quincy, Mass., a harborside town 10 miles south of Boston, and will be arraigned on murder charges.

Time will tell if the courts find the alleged Craigslist Killer guilty.
