LOS ANGELES — A “security hold” has been put on the results of the autopsy of pop legend Whitney Houston, the LA county coroner’s office said Sunday, adding there were “no signs of foul play” in her death.

Houston, whose massive hits included “I Will Always Love You” but whose career went downhill as she battled with drugs, was found dead in her room at the Beverly Hilton on Saturday. She was 48.

“At this time... there’s no signs of foul play,” Ed Winter, the assistant chief coroner for Los Angeles County, told reporters, echoing a police report from Saturday.

When asked about reports that Houston, 48, had several prescription drug bottles in her room, Winter said: “I’m not going to comment on any of the meds or prescriptions that were obtained. As I said, it is a security hold.”

He said the security hold was used in high-profile cases such as the deaths of pop icon Michael Jackson and actress Brittany Murphy.

Winter added that it could take six to eight weeks for toxicology results to be made public.

Asked about whether suicide was being investigated, Winter said: “We’re looking at all aspects of the case and hopefully maybe by Wednesday or Thursday this next week,” more information might be available.
