Police are investigating Whitney Houston's death at the Beverly Hilton Hotel; at 3:55pm PT Saturday, the singer was pronounced dead in a fourth-floor hotel room, with no immediately apparent cause of death.

There were "no obvious signs of criminal intent," Beverly Hills Police Department Lt Mark Rosen said today at a press conference.

Rosen said Houston's body would lie in situ and that the coroner's office would eventually take over the investigation.

When asked if drugs were found in the room, Lt Rosen said the investigation was "too fresh" and that there could be no speculation on the cause of death. Reporters were told the individuals who called 911 were part of the singer's "entourage."
