Aaron Carter Cause of Death Released: Drowning After Huffing Aerosol Dusters

Singer Aaron Carter's official cause of death is "drowning" in his bathtub, while under the influence of an aerosol duster and powerful sedative Xanax.

According to the Los Angeles County Coroner's Office, the 34-year-old singer was found submerged underwater and unresponsive in his bathtub by a housekeeper, who was knocking at the door to offer him coffee.

Toxicology tests following his death revealed the presence of "difluoroethane" which is commonly found in aerosol dusters and compressed air cans. "Difluoroethane is a gas commonly used as a propellant in air spray cleaners for electronic devices that can induce feelings of euphoria when inhaled. It is known to have cardiotoxic effects which can lead to cardiac arrhythmias and sudden cardiac arrest," the report states.

Also, a common benzodiazepine -- Xanax-- was found in his system. It states, the drug "has depressant effects on the central nervous system which can cause drowsiness and sedation."

Additionally, anti-histamine and quetiapine metabolites were present" in his body. It should be noted, "quetiapine" is used to treat depression and is labeled an anti-psychotic.

As for how the drowning happened, the report indicates "based on the autopsy findings, investigative reports, and circumstances, as currently known, Mr. Carter became incapacitated while in the bathtub due to the effects of inhaling compressed gas and taking alprazolam." Adding, "This resulted in him becoming submerged under water, unable to breathe, and ultimately led to his death. The cause of death is drowning due to the effects of difluoroethane and alprazolam. The manner of death is an accident."

Shockingly, the report describes a terrible scene at Carter's home, including sad details of his current surroundings.

"The residence was scarcely furnished; most of the furniture was in the garage. (Aaron's) bedroom and music room appeared to be fully furnished. His bedroom was messy; the nightstands were dirty, and the drawers were in disarray. There were air canisters on the bed and in the bathroom," a first responder wrote.

He continued, "Multiple bottles of prescription medication were found in the drawers and an unlocked safe was found in the bathroom. There was fecal matter in the closet."

The Coroner's report described the bathtub and scene, saying, "The water in the bathtub was green and there was grime around the edge of the tub." And, "A nozzle tip to one of the duster cans was found in the front pocket of the sweatshirt found on the floor near him."

Officers responding to the scene interviewed the mother of Aaron's child, Melanie Martin, who told them that she called in a "welfare check" about a week earlier -- because he had fallen off the wagon. It states, "The decedent wanted to go to rehab in Florida, but he couldn't leave California until 12/11 due to a court date/drug program commitment. She knew the decedent relapsed this year and said that called his sister about a month ago to tell her the decedent was huffing."

In the week prior to his death, Aaron's fiancée called the police, "requesting deputies conduct a welfare check on him because she believed he was under the influence while driving his RV." But, after speaking to him, Carter was not arrested for driving under the influence.

Unfortunately, he also missed a meeting with his drug counselor earlier in the day.
