Coincidentally, around the time of the 1968 Democratic National Convention much of the photographic evidence related to 1968 Democratic presidential primary candidate and U.S. Senator from New York Robert Kennedy's elimination was apparently burned. According to The Kennedy Encyclopedia by Caroline Latham and Jeannie Sakol:
"In August 1988, the state of California released much of its documentation of the investigation of Senator Robert F. Kennedy's assassination on the night of June 5, 1968. Among the more than 50,000 pages of material was a certificate attesting to the fact that 2,410 photographs taken during the investigation were burned on August 21, 1968, little more than two months after the shooting. The Los Angeles Police Department said they did not know why the photographs were destroyed. Scholars have labeled the burning `incredible' and suggested it might be the resultt of something more sinister than mere incompetence."
