James "Whitey" Bulger, the convicted Boston mobster whose rise and fall was as convoluted as any Hollywood script, goes before a judge Wednesday with prosecutors calling for him to be locked away for life.

The 84-year-old Bulger was found guilty of racketeering, extortion and money laundering in August after a rancorous two-month trial, with a federal jury linking him to 11 killings. Federal prosecutors have urged District Judge Denise Casper to hand down a life sentence for the longtime fugitive, calling him one of the city's "most violent and despicable criminals."
