A Missouri man is in custody after being charged with threatening a mass shooting at a weekend screening of the latest “Twilight” movie as well as at a local Wal-Mart.Blaec Lammers, 20, of Bolivar, Mo., was arrested on charges of making a terrorist threat, armed criminal action and attempted first-degree assault. He is being held at Polk County Jail. The News-Leader in Missouri reported that he was charged Friday in a local court. According to a probable cause statement, Lammers’ mother contacted Bolivar police on Thursday, concerned that weapons that Lammers had purchased were similar to ones used in the Aurora Colorado movie theater shooting. “His mother further stated that with the opening of the new ‘Twilight’ movie she was concerned that Blaec Lammers may have intentions of shooting people at the movie,” according to the police statement. The authorities said that they had been told that Lammers had recently purchased two assault-type rifles and was “off his medication.” A Bolivar officer contacted Lammers at a local eatery, and he agreed to come in for questioning. Although Lammers initially said that he bought the guns to go hunting, Bolivar police said he eventually stated that he had purchased tickets for a Sunday showing of “The Twilight Saga: Breaking Dawn — Part 2″ and was “going to shoot people at the movie theatre on that night.” “Blaec Lammers stated that he had a lot in common with the people that have been involved in those shootings. Blaec Lammers stated that he was quiet, kind of a loner, had recently purchased firearms and didn’t tell anybody about it, and had homicidal thoughts,” the police statement said. He also told police that he had concerns that he would run out of ammunition, having told them that he purchased 400 rounds, and that he instead was planning to shoot people at a local Wal-Mart, according to the police statement. The statement says that Lammers in 2009 had threatened a Wal-Mart employee, and followed an employee around the store before he was contacted by officers.
