A car parked illegally outside a Dunkin' Donuts -- and drugs and a loaded handgun plainly visible in bags on the rear seat -- led to the arrest of a man and woman on drug and weapon possession charges early Tuesday morning in Baldwin, police said.

Nassau County police said Justin R. Coleman, 24, of 27 Wallace St., Freeport, and Jennifer G. Chavez, 27, of 864 Goodrich St., Uniondale, were arrested after an investigation by officers who saw the illegal items outside the doughnut shop at 12:40 a.m.

Coleman was charged with three counts of criminal possession of a weapon and criminal possession of a controlled substance, while Chavez was charged with unlawful possession of marijuana, police said.

Police said Bureau of Special Operations officers saw the pair standing next to the 1996 Nissan in the lot of the Dunkin' Donuts on Grand Avenue.

The officers then saw an open pocketbook containing the marijuana and a loaded silver handgun in an open black knapsack, police said.

According to police, a search found that the gun, which was loaded with four 9-mm rounds, had been defaced -- the serial numbers filed off. A plastic bag containing crystal methamphetamines also was recovered, police said.

A search of Coleman also recovered a handgun magazine containing two 9-mm rounds, police said.

No injuries were reported.

Both Coleman and Chavez were scheduled for arraignment Tuesday in First District Court in Hempstead.
