Aaron Carter’s death caused chaos inside his Los Angeles home … as his housekeeper was heard screaming over the police scanner after discovering his body. TMZ has obtained police audio of the moment the housekeeper found Aaron unresponsive in his bathtub Saturday morning and frantically called 911. The 911 operator stated in the audio clip that FIRE/EMS units were needed at Aaron’s home for a “female scream” and made a cryptic reference to “in the bathtub.” When paramedics arrived on the scene, Aaron was already dead. Authorities have not released an official cause of death, but law enforcement sources tell TMZ police will do a thorough investigation into prior drug use. Investigators were seen carrying Aaron’s body in a body bag outside his home and loading him into the back of a truck marked “Coroner.” TMZ broke the story of Aaron’s death … police responded to his Lancaster home after receiving a 911 call at 11 a.m. Saturday that a male had drowned in the bathtub. Aaron’s fiance Melanie Martin later told TMZ … “My fiance Aaron Carter has passed away. I love Aaron with all my heart and it’s going to be a journey raising a son without a father. Please respect the family’s privacy me as we come to terms with the loss of someone we love dearly. We are still in the process of coming to terms with this unfortunate reality. Your thoughts and prayers are greatly appreciated.” Aaron rose to prominence in the late 1990s as a pop singer, releasing four studio albums, starting with his self-titled debut album in 1997, when he was just 9 years old.
