The Los Angeles County Department of Medical Examiner said the 29-year-old basketball player’s death was accidental. Clarke was found dead inside a home near Los Angeles on May 11. About six weeks before he died, Clarke was arrested in Arkansas on charges of speeding, reckless driving and possessing a controlled substance. He was with Memphis for all seven of his pro seasons after finishing his college career at Gonzaga.
