Andre Young Jr., 20, was discovered "unresponsive" by his mother at his home in Woodland Hills, Calif., on Saturday morning, according to the L.A. County Coroner's office.
"Dr. Dre is mourning the loss of his son," his rep Lori Earl says in a statement. "Please respect his family's grief and privacy at this time."
Young's mother told police that she attempted to rouse her son at 10:24 a.m. on Saturday, and when she couldn't, she called paramedics. They pronounced him dead at the scene.
Young "had been out with friends" the previous night and returned home around 5:30 a.m., according to L.A. County Coroner's assistant chief Ed Winter. An autopsy was performed Monday. No foul play is expected.
