Over a month has passed since the death of Whitney Houston on Feb. 11, and there’s still no official word on what caused it.
Sources told the L.A. Times on Tuesday the investigation still could take several weeks to close, with no specific date given for when results are expected.
Currently, investigators are awaiting the results of toxicology reports and gathering information from subpoenas issued to doctors and pharmacies. Authorities found several bottles of prescription medication in the room at the Beverly Hills Hilton where the singer, 48, was staying.
Houston’s cousin, singer Dionne Warwick, said on Tuesday she believed the pop star died of a heart attack, and wasn’t sure whether drugs played a part.
