Investigators say a post mortem on R&B singer Teena Marie has revealed no signs of trauma, and said it could be weeks before the cause of her death is determined.
Los Angeles County Assistant Chief Coroner Ed Winter said that toxicology tests that could determine the star's cause of death take about six weeks.
He said her body showed no signs of trauma and no illegal drugs were found in the Pasadena home where she died.
Teena, the singer of hits like Lovergirl who was often called the "Ivory Queen of Soul", was found unresponsive by family members in her home on Sunday. She was 54.
Police said in a statement that the death appeared to be from natural causes.
