An autopsy on a woman whose body was found in a hotel water tank in Los Angeles is complete, but the cause of death is deferred pending further examination, the Los Angeles County Coroner's Office said Thursday.

That may take six to eight weeks, according to Ed Winter, the assistant chief of the coroner's office.

The decomposing body of Elisa Lam, 21, of Canada, was found floating inside a water tank on the roof of the Cecil Hotel on Tuesday. The body was in the tank for as long as 19 days while guests brushed their teeth, bathed and drank with water from it, officials say.
