There were no witnesses to Bono's fatal accident….
The retired FBI agent is now calling for the authorities to dig up Bono's remains and open a homicide investigation. Gunderson's efforts have been backed by top forensics experts, who fear Nevada authorities were too quick to mark the tragedy as a skiing accident, and investigator Bob Fletcher, who has confessed he sent evidence of a 10-year study that linked top U.S. government officials to arms and weapons dealers to Bono less than a month before his death. Fletcher says, "He was going to make it his number one priority… There's no doubt in my mind Sony was murdered by someone who needed him silenced."
