Blaec Lammers was charged with first-degree assault, making a terroristic threat and armed criminal action after he was arrested Thursday. Police in Bolivar, Mo, said Lammers’ mother contacted them Thursday worried that her 20-year-old son had bought weapons similar to ones used in the Aurora, Colo shooting that killed 12 moviegoers in July at a midnight screening of The Dark Knight Rises.

According to the Springfield News-Leader, officers detained Lammers, who according to a police statement said he had purchased two assault rifles and 400 rounds of ammo earlier in the week for hunting, then said he had “a lot in common with the people that have been involved in those shootings”, and that he had homicidal thoughts. He eventually said he bought tickets to a Sunday screening of The Twilight Saga: Breaking Dawn Part 2 with the intent of shooting people in the theater.

Lammers later said he decided to do the shooting at a local Walmart because he could get more ammunition there when he ran out. According to the paper, the felony complaint accuses Lammers of having “knowingly communicated to Dustin Ross (Bolivar police officer) a threat to cause shoot (sic) people at the Bolivar Walmart Store, an incident involving a danger to life, by stating the same to him, and the defendant did so for the purpose of frightening ten or more people.”
