We're told Beverly Hills detectives are not investigating rumors that someone removed cocaine from the room, because they're convinced it wasn't removed.
Sources directly involved in the investigation told TMZ early on that no illegal drugs were recovered from the room. TMZ has circled back with these sources who now tell us they were unaware at the time that cocaine was present.
