Maybe he used that apartment as a large safety deserve. The cash was in the wall he probaly had millions. He got the apartment I think a few years before the pinch. Probaly had 2+ mill cash there. Whatever you say or think about Bulger he was smart. Me personally think if he was Italian would have had jerry n Larry make him no doubt. Guy loves killing prison money dressing nice pinky rings n caddy's. Say no more.
