FILE - Hotel Cecil in Los Angeles is seen in a Wednesday Feb. 20, 2013 file photo. Police say the body of a missing Canadian woman was found Tuesday at the bottom of one of four cisterns on the roof of the hotel. The tanks provide water for hotel taps and would have been used by guests for washing and drinking. Los Angeles County Department of Public Health officials were expected to release the results of tests on the water on Thursday, Feb. 21. Investigators used body markings to identify 21-year-old Elisa Lam, police spokeswoman Officer Diana Figueroa said late Tuesday. (AP Photo/Nick Ut, File)
