We’ll have to wait some time before finding out what the autopsy on singer Whitney Houston revealed. E! reports that the Beverly Hills Police Department has place a security hold on the results, though they do say that there were no signs of criminal intent. The coroner's office confirmed this in a press conference. Toxicology tests, however, will take weeks to complete. Houston was found in the bathtub of her room in the Beverly Hilton Hotel. Drowning is reportedly one the scenarios being investigated.
