KANSAS CITY, Mo. — A man accused of plotting to open fire inside a Missouri movie theater during a "Twilight" showing and then attack nearby Walmart was arrested in 2009 after following around a clerk at the same store with a knife and rubber mask, according to an arrest report released Tuesday.
Blaec Lammers went to the Walmart store in Bolivar looking for an "easy victim" in October 2009 after watching the horror film "Halloween," telling investigators that watching the main character killing people "got him to thinking," the report said.
Lammers told authorities he had watched the clerk for more than two hours. He said he was planning to follow the clerk into a storage room and kill him when he heard his name over the public address system and his father calling his name, according to the report.
No charges were filed in that case. Instead, Lammers, who was 17 at the time, was committed for 96 hours for a mental health examination, Polk County prosecutor Ken Ashlock said Tuesday. Ashlock, who was not the county's prosecutor in 2009, said he didn't know what happened after the commitment.
Lammers, now 20, made his first court appearance Tuesday in the movie theater case and was ordered to undergo a mental health exam. Lammers, who is being held on a $500,000 bond, is charged with first-degree assault, making a terroristic threat and armed criminal action.
His public defender, DeWayne Franklin Perry, declined comment Tuesday.
Lammers was arrested last week after his mother contacted police, saying she was concerned that her son "may have intentions of shooting people" during the opening weekend of the final film in the popular vampire movie series.
According to a police probable cause statement, she said she believed her son had amassed weapons similar to those used by the gunman who attacked a theater in Aurora, Colo., during the latest Batman movie in July. That attack killed 12 people.
Investigators later determined Lammers had recently purchased two assault rifles and 400 rounds of ammunition.
Lammers' parents also tipped off authorities about the previous Walmart incident. The 2009 police report said Lammers' mother called authorities after finding a suicide note from her son and a missing knife. An officer was en route when the mother said her son's vehicle had been found in the parking lot of the Walmart store in Bolivar, a town about 130 miles southeast of Kansas City.
The parents said in 2009 that Lammers had been diagnosed with depression, and his mother said Lammers had an appointment that day with his psychologist and "he has been acting different since then."
According to a probable cause statement in the movie theater case, Lammers was questioned Thursday afternoon and told authorities he bought tickets to a Sunday "Twilight" screening in Bolivar and planned to shoot people inside.
Lammers also said he planned to "just start shooting people at random" at the Walmart store less than a mile away, so if he ran out of bullets, he could "just break the glass where the ammunition is being stored and get some more and keep shooting until police arrived," investigators wrote.
The probable cause statement also said Lammers was "off of his medication."
