Tonight on AC360°, we have new details on the medical student accused of being the so-called "Craigslist Killer."
We've learned Philip Markoff, 23, is on suicide watch at the Boston jail.
Markoff's suspected of killing a masseuse at a Boston hotel and robbing another at gunpoint. He has pleaded not guilty to the charges.
There's more on case. Randi Kaye just returned from Boston and will have a live report on the new developments.
