Jefferson City police say a 26-year-old man has been charged with making a terrorist threat.
Brian Groner, of Jefferson City, was charged Thursday with posting the threats on his Facebook page.
The Jefferson City News-Tribune reports a probable cause statement says Groner's posts included "''Your Next Mass Shooter. Columbine won't have (expletive) on me."
He also said the shooters at Columbine High School in Colorado in 1999 were "lame" because they killed "only" 12 people and he could do better.
The statements were posted on a setting that allowed anyone to view them, and police say more than 10 people reported the comments to authorities.
Police said in a statement that Groner was "hostile" when he was arrested at home Wednesday but admitted to "understanding the gravity of his statements."
