Former mob boss James "Whitey" Bulger's personal possessions - including a pen holder designed to look like a rat and a three-carat, heart-shaped diamond ring - fetched more than $100,000 at an auction in Boston on Saturday. Law enforcement officials sold off hundreds of items seized when federal agents captured the fugitive mobster in an apartment in Santa Monica, California, in 2011. Bulger, 86, ruled Boston's criminal underworld for a quarter-century before going on the lam after a corrupt FBI agent alerted him that he was about to be arrested.
