Police in Maryland say they may have prevented another shooting with the arrest of a man who made violent threats and was found to have a large stockpile of weapons. The suspect, Neil Prescott, had reportedly called his workplace and made threats referring to himself as the “joker,” just as James Holmes had allegedly called himself upon his arrest in Aurora. Maryland police and Bureau of Alcohol, Tobacco and Firearms officials described the raid on Prescott’s home.

Prince George’s County Police Chief Mark Magaw: “He made significant threats to coming back and harming people at the business. In fact, he said, ’I’m a joker, and I’m going to load my guns and blow everyone up.’ That initiated a 36-hour investigation that culminated early this morning.”

Ashan Benedict, ATF Baltimore Field Division: “We had several agents out there right on the scene. They evaluated the evidence. They recovered approximately 25 firearms, several thousand rounds of ammunition. The firearms are further described as semi-automatic rifles, semi-automatic pistols.”
