“We need additional testing,” Coroner Assistant Chief Ed Winter told reporters. “We won’t make that final determination until all the tests are in.”
Citing a security hold on the case, Winter would only confirm that Houston’s body was found in the bathtub in her hotel room at the Beverly Hilton.
“There were no visible signs of trauma on the body,” he said.
Winter declined to address rumors that the singer may have drowned, who initially discovered her body, or if there were any prescription or illegal drugs in her room.
