*Police investigating the death of Whitney Houston found traces of cocaine in the Beverly Hills hotel room where the pop diva died last month.

According to TMZ, documents from investigators do not reveal the quantity of the drug found but say simply that among the items recovered by police was “white, powdery remnants” that ended up testing positive for cocaine.

The L.A. County coroner revealed last week that accidental drowning was the official cause of Houston’s death, adding that cocaine use and heart disease were contributing factors. According to the coroner’s report, traces of cocaine were found in Houston’s system at the time of death, along with Xanax, Flexeril, marijuana and Benadryl, which officials said played no role in her death.

At the time, it was reported that no cocaine was found in the singer’s room when she died, but coroner spokesman Craig Harvey noted that cocaine metabolites were found in her system, leading them to conclude that Houston was a chronic user of the drug.

TMZ also reported that Beverly Hills Police detectives are not investigating the rumors that a friend of Houston’s allegedly removed cocaine from the room following her death because they are not convinced evidence of the drug was swept away before their arrival.
