A man parked for a long time in a gas station lot was arrested Wednesday night after a Madison police officer saw a handgun sticking out of the man's pocket.

Police said the man, Dominique Gaunichaux, 20, of Madison, is a convicted felon, and is not allowed to have a gun.

He was tentatively charged with possession of a firearm by a felon and carrying a concealed weapon, Madison police said.

The arrested was made at about 7:30 p.m. at a gas station in the 4600 block of Verona Road.

"Officers made contact with the suspect after he remained parked for a period of time in the lot of a gas station, without buying gas or going inside to make a purchase," said police spokesman Joel DeSpain.

An officer talking with Gaunichaux noticed the grip of a handgun sticking out of the man's coat pocket.

"It turned out to be a 9mm Smith and Wesson, with 16 rounds in the magazine," DeSpain said.
