Springfield, MO – An off-duty firefighter confronted a man with a gun decked out in body armor at a Walmart store on Thursday, then held him at gunpoint until police arrived.
The incident occurred at approximately 4 p.m. at the Walmart store on Republic Road, KYTV reported.
The suspect, later identified as 20-year-old Dmitriy Andreychenko, was carrying a rifle, a handgun, and over 100 rounds of ammunition when he walked into the store, NBC News reported.
Witnesses called 911 and reported the situation as a possible active shooter, Springfield Police Lieutenant Mike Lucas told the news outlet.
“A male wearing a bulletproof vest and AR around his neck just walked into the store and is recording himself,” one caller told dispatch, according to ABC News.
"He walked in here, heavily armed with body armor on, in military fatigues, and caused a great amount of panic inside the store," Lt. Lucas continued, before referencing two recent mass shootings. “Obviously, what's happened in Texas and Dayton and all that kind of stuff in the last seven days — that’s on everybody’s minds."
After entering the store, Andreychenko grabbed a cart and began pushing it around the aisles while recording himself with a cell phone, KYTV reported.
The Walmart manager pulled a fire alarm, and yelled for the customers inside the store to evacuate the building, Lt. Lucas told NBC News.
Andreychenko also made his way out of one of the emergency exits, where he was intercepted by an off-duty firefighter, KYTV reported.
The firefighter held the suspect at gunpoint until police arrived at the scene.
Officers descended on the store within three minutes of receiving the first call about the incident.
No shots were fired, and no one was injured during the chaos, KYTV reported.
“He’s lucky to be alive, to be honest,” Lt. Lucas said.
“He certainly had the capability [and] the potential to harm people,” he added, according to CNN.
Open carry is legal in Missouri, as long as the individual doesn’t display them in a threatening manner, NBC News reported.
On Friday morning, the Springfield Police Department (SPD) tweeted that Andreychenko was arrested for first-degree making a terroristic threat.
The investigation into the incident is ongoing, and the man’s potential motive has not been released.
