Philip Markoff, the Boston University medical student suspected of killing a NYC woman at a Boston hotel, has been put on suicide watch. ABC News reports that prison officials apparently found shoelace marks around the 23-year-old's neck, "Markoff was moved from the general population of Boston's Nashua Street jail to a segregated unit where officers can keep a constant eye on him." In the meantime, the father of Markoff's fiancee Megan McAllister told reporters, "She's still confident in Phil. Other than that we’re saying a lot of prayers." Also: A Facebook page has been created: "Phil Markoff is Innocent Until Proven Guilty."
