Rafer Johnson, 1960 Olympic Decathlon Champion, Dies at 86 Associated Press LOS ANGELES - Rafer Johnson, who won the decathlon at the 1960 Rome Olympics and helped subdue Robert F. Kennedy's assassin in 1968, died Wednesday. He was 86. He died at his home in the Sherman Oaks section of Los Angeles, according to family friend Michael Roth. No cause of death was announced. Johnson was among the world's greatest athletes from 1955 through his Olympic triumph in 1960, winning a national decathlon championship in 1956 and a silver medal at the Melbourne Olympics that same year. His Olympic career included carrying the U.S. flag at the 1960 Games and lighting the torch at the Los Angeles Memorial Coliseum to open the 1984 Games. Johnson set world records in the decathlon three different times amid a fierce rivalry with his UCLA teammate C.K. Yang of Taiwan and Vasily Kuznetsov of the former Soviet Union. Johnson won a gold medal at the Pan American Games in 1955 while competing in just his fourth decathlon. At a welcome home meet afterward in Kingsburg, California, he set his first world record, breaking the mark of his childhood hero, two-time Olympic champion Bob Mathias. Devoted to Kennedy On June 5, 1968, Johnson was working on Kennedy's presidential campaign when the Democratic candidate was shot in the kitchen of the Ambassador Hotel in Los Angeles. Johnson joined former NFL star Rosey Grier and journalist George Plimpton in apprehending Sirhan Sirhan moments after he shot Kennedy, who died the next day. "I knew he did everything he could to take care of Uncle Bobby at his most vulnerable moment," Kennedy's niece, Maria Shriver, said by phone. "His devotion to Uncle Bobby was pure and real. He had protected his friend. Even after Uncle Bobby's death he stayed close." Johnson later called the assassination "one of the most devastating moments in my life." Born Rafer Lewis Johnson on August 18, 1934, in Hillsboro, Texas, he moved to California in 1945 with his family, including his brother Jim, a future NFL Hall of Fame inductee. Although some sources cite Johnson's birth year as 1935, the family has said that is incorrect. They eventually settled in Kingsburg, near Fresno in the San Joaquin Valley. It was less than 25 miles from Tulare, the hometown of Mathias, who would win the decathlon at the 1948 and 1952 Olympics and prove an early inspiration to Johnson. Johnson was a standout student and played football, basketball, baseball and track and field at Kingsburg Joint Union High. At 6-foot-3 and 200-plus pounds, he looked more like a linebacker than a track and field athlete. .
