Officers responded to a call of an active shooter at the Walmart Neighborhood Market in Springfield, police Lt. Mike Lucas said.
But no shots were fired and no one was injured, police said.
“All we know is the fact that he walked in here heavily armed with body armor on, in military fatigues and caused a great amount of panic inside the store. So he certainly had the capability the potential to harm people,” Lt. Lucas said.
At least one person was hurt after an out-of-control hot air balloon ripped through a crowded festival in Missouri on Saturday after organizers said an “experienced balloonist” grazed a tree.
Video taken of the incident at the Hannibal Bicentennial Celebration in Hannibal, a city roughly 120 miles northwest of St. Louis, shows a crowd of people watching as a green and black hot air balloon in the air heads toward them.
A young girl was knocked down during the landing incident, the committee overseeing the celebration told Fox News on Sunday.
