<begin quote>
On June 24 and September 22 1975 Roselli testified before the 1975 U.S.
Senate Select Committee on Intelligence (SSCIA) led by Idaho Senator Frank
Church about the CIA plan to kill Castro, Operation Mongoose. Shortly before
Roselli testified, an unknown gunman shot and killed the disgraced Giancana
in the basement of his Oak Park, Illinois home. This happened just days
before Giancana was to testify before the committee. Giancana's murder
supposedly prompted Roselli (whose own power base disappeared with
Giancana's death) to permanently leave Los Angeles and Las Vegas for Miami,
Florida.
On April 23, 1976, Roselli was called before the committee to testify about
a conspiracy to kill President Kennedy.[1] Three months after his first
round of testimony on the Kennedy assassination, the Committee wanted to
recall Roselli. However, at this point, he had been missing since July 28.
On August 3, Senator Howard Baker, a member of the new SSCIA, requested the
FBI investigate Roselli's disappearance.[1]
On August 9, Roselli's decomposing body was found in a 55-gallon steel fuel
drum floating in Dumfounding Bay near Miami, Florida. Roselli had been
strangled and shot, and his legs were sawed off. Some believed that boss
Trafficante ordered Roselli's death. According to this theory, Trafficante
believed that Roselli had revealed too much about the Kennedy assassination
and Castro murder plots during his Senate testimony, violating the strict
Mafia code of omerta (silence.)[4]

Jimmy Hoffa
In 1971 Richard "hey we were buddies about Dallas 11-22-63" Nixon commuted a
sentence for Hoffa
Frank Sheeran said he pulled the trigger on Hoffa

"In 2004, authorities in Detroit extracted floorboards from the northwest
Detroit home where Sheeran said he had shot Hoffa. However, by February
2005, the Bloomfield Township Police said that the FBI Crime Lab reported
that while it was human blood from a male on the floorboards, the blood did
not match Jimmy Hoffa's. It was later revealed that the DNA was destroyed
due to the fact that the wrong kind of Luminol was used to find the blood
remnants."
ya, right, the DNA was destroyed...and the Carcano sling swivel morphed...
Yes they were killed AFTER they testified. If it was because of the
testimony, why don't do it BEFORE they testified. That would make
sense.
