Los Angeles Country coroners have confirmed that the death of Dr. Dre's son, Andre Young Jr., was the result of an accidental heroin and morphine overdose.

"Andre Young Jr.'s death has been ruled as an accident due to morphine and heroin intoxication," media officer Ed Winter told one publication.

The 20-year-old was found in the bedroom of their Woodland Hills, CA, home by his mother, Jenita Porter, on the morning of August 23.

Porter told police that her son had come home at around 5:30 a.m., after having spent the night out with friends, but that she heard him snoring in his bedroom upon his return. Later in the morning, Porter discovered that Young was unconscious, so she called paramedics, who attempted to revive him, to no avail. He was pronounced dead at the scene.

Dr. Dre has yet to release an official statement since the news of his son's cause of death was revealed.
