Los Angeles police Det. Wallace Tennelle gave his thoughts in a deposition.
The veteran detective was answering questions posed by a lawyer for the notorious Los Angeles hotel where the 21-year-old passed her final hours.
Tennelle took the call in February 2013 about a Canadian national who was missing from the Cecil. And he had peered into the open hatch of the rooftop water tank and seen Lam’s lifeless body.
“My opinion is that she fell off her medication, and in her state, she happened to find her way onto the roof, got into the tank of water,” Tennelle told the lawyer.
“At the time, I think that water tank was maybe full. But as people used the tank, used water, unknown to her, the level was dropping to a point where she could no longer reach out and escape, and she died that way.”
