Canadian tourist Elisa Lam had been missing for about two weeks when officials at the Cecil Hotel found her body in a water cistern on the hotel roof. Guest complaints about low water pressure prompted a maintenance worker to make the gruesome discovery Tuesday, and officials were trying to determine if the 21-year-old was killed or if her death was a bizarre accident.
