Before Bono's death, Fletcher had been probing the activities of high ranking U.S. military and government officials he claims were raking in millions from arms and **** deals in Central America and Southeast Asia.
He says he sent his shocking findings of corruption, including videotaped evidence, to Bono.
"I later received a call from an assistant in his offices to tell me Sonny had seen my full report and was absolutely livid about the level of corruption I made him aware of," Fletcher tells GLOBE.
"He was going to make it his No. 1 priority when Congress resumed after the Christmas and New Year break. He was going to go after the biggest names.
"Just 10 days later, I received a call that he was dead. I'd heard it was suspected his offices had been bugged. Tragically, that must have been the case. There's no doubt in my mind Sonny was ******** by someone who needed to silence him."
