Beverly Hills PD: Whitney Houston Was NOT Murdered!!!

In case you were secretly wondering, NO ONE killed Whitney Houston ... this according to the police department currently investigating the singer's death.

A rep for the Beverly Hills Police Department -- the precinct that responded to Whitney's death scene at Beverly Hilton hotel Saturday -- just spoke at a news conference, claiming detectives are currently pursuing a death investigation ... NOT a homicide investigation.

The rep Lt. Mark Rosen adds, "This is a normal investigation for death of someone of [Whitney's] age."
