Two people were arraigned Wednesday and charged with illegally possessing a firearm, ammunition and a gun with the serial number scratched off.

Torrie Tatum, 22, and Domingo Mendes, 21, along with a 20-year-old woman were pulled over for speeding Tuesday night on Route 2 in Burlington.

When State Trooper Paul Langone was questioning Tatum, who was sitting in the backseat, he noticed a black mask. Tatum said it was a Halloween mask for his daughter. Considering its July, Langone had Tatum get out of the car. Langone frisked Tatum and found a loaded semi-automatic firearm with an obliterated serial number.

Mendes later admitted it was his gun.

The driver, Selina Salafia, was summons to court for operation after license suspension, minor transporting alcohol and speeding.

Langone is no stranger to headlines — in October 2009, police said a therapist was stabbed by her patient in a Massachusetts General Hospital building on New Chardon Street in Boston. Langone, off-duty at the time, shot the patient and saved the therapist’s life.

Tatum and Mendes are being held on a $5,000 and $10,000 bond.
