This still image taken from a security video was released on Feb. 13, 2013, by the Los Angeles Police Department in connection with the search for 21-year-old missing Canadian tourist Elisa Lam. In this image, a woman believed to be Lam quickly peeks out the door of an elevator before jumping back inside in the Cecil Hotel in downtown Los Angeles on Thursday, Jan. 31, the last day she was seen alive. A maintenance worker at the hotel found Lam's body in a water cistern on the building's roof on Feb. 19, more than two weeks after she had gone missing. (AP Photo/Los Angeles Police Department)
