Elisa Lam Dead: Missing Vancouver Woman's Body Found In L.A.

A Canadian who was last seen almost three weeks ago at a Los Angeles hotel has been found dead in a water tank on top of the building, confirmed police.

The body of Elisa Lam, 21, was found Tuesday morning in one of four tanks that hold the water supply for the Cecil Hotel. A worker, who was checking a complaint about low water pressure, discovered Lam's body.

The L.A. Police Department confirmed to The Huffington Post B.C. that Lam was positively identified by body markings.

Police say it is too early to tell if Lam was the victim of foul play.

Lam, who attended the University of British Columbia in Vancouver, was last seen on Jan. 31 at the hotel. L.A. police released surveillance video of her last week that showed her acting strangely in the hotel elevator.

Lam had been travelling alone but was in regular contact with her parents in Vancouver until she disappeared.
