BOULDER, Colo. (CBS4) — Police investigating reports of gunshots overhead in Boulder’s University Hill neighborhood at daybreak Monday morning have arrested a 21-year-old man.
Matthew Marton was taken into custody Wednesday night, the Boulder Police Department announced Thursday.
Marton, who was already out on bond for a felony menacing case in September, faces 11 charges in this new case. Those include another felony menacing charge and a felony for unlawful purchase of a firearm. The nine others are misdemeanors related to defacing a firearm, illegally firing a firearm, and aiming a weapon at people.
Police were called to the intersection of 12th Street and College Avenue at 6 a.m. Monday.
Marton, living in one of the apartments at that intersection, was quickly determined to be a person of interest, the police department stated in a press release.
After obtaining a search warrant, investigators found an Inter Ordnance AK-47 Sporter Rifle inside the apartment, nine shell casings below the apartment’s balcony, and another shell casing on a neighbor’s balcony, according to an arrest affidavit obtained by CBS4.
Marton allegedly told officers, “calm down, I’m hammered” when they placed him into custody.
A roommate told investigators that Marton had previously pointed the gun at the roommate’s chest during an argument and threatened to kill the roommate if Marton was “kicked out,” as stated in the affidavit.
Marton, while waiting in an interview at Boulder PD headquarters, admitted to an officer that he had purchased and consumed alcohol, including tequila, per the affidavit. He also admitted taking Xanax.
Consuming alcohol or controlled substances is prohibited under the conditions of Marton’s bond in the September felony menacing case, as is owning a firearm, the officer noted.
In September, Marton allegedly fired a gun outside residence in the neighborhood when he was denied entry to a party.
Marton was advised of the new charges – including new ones connected to the violation of his September bond – Thursday afternoon in Boulder County District Court. He is currently being held in the Boulder County Jail on a $100,000 bond.
