20-year-old Blaec Lammers has been arrested, accused of planning a movie theater massacre during a Sunday showing of the final "Twilight" movie.
He's been charged with 1st degree assault and making a terror threat.
His mother alerted police that he had purchased ammo and two assault rifles, similar to the Aurora, CO, movie shooter's arsenal.
