Former student arrested after bomb threat at Colorado Mountain College's Leadville campus

LEADVILLE, Colo. — It took more than 11 hours to fully investigate a bomb threat in Leadville Monday targeting the Colorado Mountain College campus.

Amid the investigation, police say they arrested the sole suspect in the threat. Tuesday, police identified the suspect as 32-year-old Adam Slattery.

Slattery was identified as a former student of the school, who hadn't enrolled in the spring semester, but was enrolled in the fall semester of the school year.

Amid the half-day investigation, police evacuated part of the campus, then held a lockout, sheltering students in the small school's cafeteria. 

Other schools — each of Leadville's public schools — also enacted emergency protocols, shielding students from potential harm.

Eventually, police learned the threat of explosives wasn't a valid threat. Colorado Mountain College called for help in the early morning around 9 a.m. after they received a call threatening explosives in the library. 

After narrowing down what campus — CMC has three — was threatened, police called in a regional bomb squad and the Department of Corrections. 

Most of the campus was evacuated as the bomb squad went to work clearing the campus, vehicles and buildings. 

Police say they located the suspect's backpack in the library and took great precaution to screen, then search it. Inside, police say they did not find any illegal items. 

Slattery faces a host of charges, including false reporting of explosives, resisting arrest, menacing, criminal extortion and harassment. 

Authorities say Slattery expressed displeasure over his grades, but wasn't cooperating with the investigation.
