In 1971, LAPD Chief of Police E.M. Davis appointed a board of inquiry to investigate allegations made against officer DeWayne Wolfer who was being considered for the chief forensic chemist position within the department. In the course of the investigation, the board examined three cases in which Wolfer had been involved, including the Kennedy assassination. Wolfer had been a witness at Sirhan's trial and had conducted the primary ballistic and bullet trajectory studies related to the case. The board focused on an examination into the techniques and procedures used by Wolfer, transcripts and evidence from the cases, and statements of outside authorities. Although only a portion of these records relate directly to the Kennedy assassination, they were stored by LAPD with the Special Unit Senator materials until their transfer to the State Archives in August 1987.
