Tragic rocker Sonny Bono was clubbed to death by hired hitmen, according to a stunning new tabloid expose. An investigator who has been researching Bono's 1998 fatal skiing accident for the past decade claims top officials linked to an international drug and weapons ring feared the singer-turned-politician was about to expose their criminal acts - and so they had him killed on the slopes. Cher's ex-husband Bono's death was listed as a "skiing accident" with family and friends satisfied he died after colliding with a tree on the piste in Nevada in January 1998. But former FBI agent Ted Gunderson tells America's Globe that there's more to the tragedy than meets the eye, after studying the autopsy reports and other evidence. He says, "It's nonsense for anyone to now try to suggest that Bono died after crashing into a tree. There's zero evidence in this autopsy report... to show such an accident happened. Instead, there's powerful proof he (Bono) was assassinated
