David Aaron Moscow faces a federal trial after making alleged threats to shoot and burn down Front Range Community College in Fort Collins.

Moscow, 30, a former FRCC student, was indicted by a federal grand jury earlier this week on 2 counts of being a felon in possession of a firearm - in addition to a pending case in Larimer County with charges of felony menacing, violation of bail bond conditions, violation of a protection order, possession of a controlled substance, and interference with a school.

Charges of possession of a weapon by a previous offender and possessing a prohibited large-capacity magazine during a crime were later dropped "in order to facilitate the federal prosecution of the firearm charges," according to Jeff Dorschner, spokesman for the US Attorney's Office.

Moscow faces up to 10 years in prison and a fine of up to $250,000 for both counts of being a felon in possession of a firearm if convicted.

In 2014, 2 years after voluntarily leaving FRCC, police were notified of an incident in which Moscow harassed a counselor at the school via voicemail.

Then in October 2015, Moscow tried to re-enroll. It was during a meeting with clinical neuropsychologists that he allegedly revealed his threats against FRCC.

Moscow was arrested October 23 for mental health hold. Fort Collins Police conducted searches the same day, finding an AR-15 semi-automatic rifle, loaded 30-round magazines, and illegal drugs in his home, in addition to a Glock .40-caliber semi-automatic handgun with 29-round magazine and 2 additional magazines in his car.

Moscow has a prior felony conviction for aggravated DUI in 2007 in Arizona. He was not allowed to own guns.
