The United States House of Representatives Select Committee on Assassinations (HSCA) was established in 1976 to investigate the assassinations of John F. Kennedy and Martin Luther King, Jr. The HSCA completed its investigation in 1978 and issued its final report the following year, concluding that Kennedy was probably assassinated as a result of a conspiracy. While the basis for that finding of "probable conspiracy" was a since-discredited acoustic analysis of a police channel dictabelt recording, the HSCA also commissioned numerous other scientific studies of assassination-related evidence that corroborate the Warren Commission's findings.
