From a New York Times obit by Richard Sandomir headlined “Paul Schrade, 97, Who Was Wounded When Robert Kennedy Was Slain, Dies”:

Paul Schrade, a prominent union official who was wounded in the fusillade of bullets that killed Senator Robert F. Kennedy in 1968, and who believed that a second gunman, in addition to the convicted assassin, Sirhan B. Sirhan, fired shots that day at the Ambassador Hotel, died at his home in Los Angeles.
