Summary  
The documents detail multiple aspects of Robert F. Kennedy’s assassination investigation, including witness accounts, forensic analysis, and juvenile supervision records. Crispin Curiel Gonzalez, a 16-year-old under probation in Los Angeles County, was noted for his unstable behavior, alleged involvement in narcotics smuggling between El Paso, Texas, and Mexico, and interactions with the Camacho family in California. His father resided in Colima, Mexico. Gonzalez’s juvenile supervision included placements at Boys Oasis and Manhattan Project Residence (MPR), where he attempted suicide twice in May 1968. The FBI was referenced in reports about his alleged smuggling activities.  

Witnesses described the assassination of RFK on June 5, 1968, during a campaign event at the Parker Center in Los Angeles. Sirhan Sirhan was identified as the suspect, who fired multiple shots with pauses between them and was subdued by security forces. Medical personnel arrived approximately 15 minutes after the shooting. Sirhan underwent a polygraph examination in June 1968, where he lied about purchasing a gun. His trial began on June 28, 1968, in Los Angeles Superior Court due to security concerns.  

FBI laboratory analysis of audio recordings from July 1968 concluded that the voice on K21 (an interview with Sirhan Bishara Sirhan) was unsuitable for comparison due to poor quality. Analysis of K20 and Q27 (a radio show portion from Oakland, California) indicated the anonymous caller’s voice differed significantly from Sirhan’s. The recordings were returned to the Los Angeles FBI office via registered mail.
