Cause of death to rap heavyweight’s son still unknown
 It could be several weeks before the cause of Dr. Dre’s son’s death is known. The L.A. County Coroner says further tests have been ordered, since the reason for Andre Young Jr.’s passing wasn’t revealed in an autopsy. He was found unresponsive by his mother this past weekend after he’d reportedly been out with friends. Jenita Porter, Young’s mom, says she’d heard her son snoring a few hours earlier at about 5:30 a.m. “We don’t know yet why he died,” police Capt. Ed Winter tells People magazine. “There were no signs of trauma or foul play. We’ll be doing toxicology and other tests, which will take up to six weeks.” Young was 20.
