A camouflage-clad Fairfield teen toting what was reported to be a "rifle" -- but proved to be a pellet gun -- in wooded area near Sasco Creek on Wednesday afternoon was charged with discharging a firearm in an open space, police said.

William Matson, 18, of Arbor Terrace, was charged after a witness called police, and three officers were dispatched to search the open space with the help of a K-9 team.

What sounded like a gunshot alerted officers to Matson's location in the woods, police said, and he put down the gun without incident.

In Matson's Subaru Forester, parked just outside the woods, the officers also found a 12-gauge over/under Mossberg shotgun, along with a box of shells, according to Sgt. Suzanne Lussier, a Fairfield police spokeswoman.

Matson was not booked at police headquarters because discharging a firearm in an open space is an infraction with a fine that can be paid by mail.
