Future: I'm No Help In Ex-Bodyguard's Murder Case

Future is a total dead-end for cops looking for a lead on who gunned down his former bodyguard, Michael Phillips.

Sources close to Future tell us he's devastated by Big Mike's sudden death but hasn't worked with him since 2012.

We're told Future has no information about what went down in the moments leading up to Mike's death. But at the same time we're told he refuses to talk to cops ... even to say he knows nothing.

As we previously reported, the police have several leads but no suspects. They're opening up the Rolodex, hoping Big Mike's contacts might provide some clues.
