A deranged Missouri man threatened to kill students at a high school “in the name of Kyle Rittenhouse,” police said. Mitchell Lovelace, 27, posted on Snapchat Saturday that he planned to shoot up Festus High School in honor of the Illinois teen, according to charging documents cited by the St. Louis Post-Dispatch. Rittenhouse, 18, was acquitted of all charges last month in the shootings that killed two men and wounded a third during unrest in Kenosha, Wisconsin, in August 2020.
