Rodney King, whose beating by Los Angeles police in 1991 was caught on camera and sparked riots after the acquittal of the four officers involved, was found dead in his swimming pool Sunday, authorities and his fiancee said. He was 47. Police in Rialto, California, received a 911 call from King’s fiancee, Cynthia Kelly, about 5:25 a.m., said Capt. Randy De Anda. Responding officers found King at the bottom of the pool, removed him and performed cardiopulmonary resuscitation until paramedics arrived. He was pronounced dead at a local hospital, police said. There were no preliminary signs of foul play, De Anda said, and no obvious injuries on King’s body. Police are conducting a drowning investigation, he said, and King’s body would be autopsied.
