LOS ANGELES (Reuters) - The 20-year-old son of veteran rapper Dr. Dre died in August from an overdose of heroin and morphine, the Los Angeles County coroner's office said on Friday.
Andre Young Jr was found dead by his mother at his Los Angeles home after spending a night out with friends.
After toxicology and other tests, the coroner ruled his death as accidental and says the case is closed, spokesman Larry Dietz said on Friday.
Dietz said the tests showed Young died of morphine and heroin intoxication.
Dr. Dre, 43, whose real name is Andre Young, rose to stardom in the 1980s as a member of the "gangsta" rap group N.W.A. He embarked on a successful solo career, winning the first of four Grammys in 1994 for a tune from his chart-topping debut "The Chronic."
He founded the rap labels Death Row Records and Aftermath Entertainment, and made stars out of such proteges as Snoop Dogg and Eminem.
At the time of his son's death, Dr. Dre issued a statement asking for respect and privacy.
