Police: Guy was driving around Hyde Park with $36,000 in cash - as well as lots of Xanax, pot and a loaded gun

Boston Police report drug-unit officers staking out Hyde Park Avenue and Arlington Street around 6:40 p.m. on Tuesday spotted what they were expecting to see: A drug deal going down, between occupants of two cars.

Officers split up to stop both vehicles. In one, police say, they found a man with "a medium sized plastic bag of marijuana," which he told them he'd just bought from one of the occupants in the other car. Officers at the other car probed that driver, who "eventually reached back into his vehicle and retrieved a medium sized plastic bag of marijuana, which he claimed he bought from the individual who left in the gray motor vehicle. "

But then, police say, the officers noticed an "abnormally large bulge" in the man's pants, not because he was happy to see them but because it turned out he had "a black Smith and Wesson M&P Bodyguard .380 Firearm" in his front pocket - and it had three live rounds in the magazine, police say. A further search of him and his car yielded $35,763 in cash, a large plastic bag with 166 Xanax pills, three large bags of marijuana, a medium bag of marijuana and drug paraphernalia, police say.

The man, not identified by police, was charged with distribution of Class D drugs, possession of Class D drugs with intent to distribute, possession of Class C drugs with intent to distribute, unlawful possession of a firearm, unlawful possession of a loaded firearm, unlawful possession of ammunition and possession of a firearm in the commission of a felony, police say.
