Elisa Lam Foul Play Not Determined


The Los Angeles Police Department has had to deny recent rumours that foul play has been ruled out in the death of Vancouver student Elisa Lam.

On Monday, some media in Vancouver reported that police investigators don't suspect foul play in Lam's death.

However, Alex Martinez, a LAPD public information officer, denied those reports to The Vancouver Sun.

He said there is no update since an autopsy last week could not definitively reveal if the 21-year-old woman was killed or died accidentally. Lam's body was found in a water tank on the roof of a downtown L.A. hotel.

The L.A. County Coroners' Office is waiting for results of toxicology and other tests which are expected to take several weeks.

Lam, a former University of British Columbia student, travelled alone to Los Angeles on Jan. 26 and was last seen by hotel staff on Jan. 31. Police revealed surveillance video of Lam acting strangely in an elevator.

It's unclear why she was in California. Her body was found about three weeks later.
