The Springfield Police Department says it responded to a call of an active shooter at the Walmart Neighborhood Market at Republic Rd., near Golden Ave., Thursday evening.

Officers booked Dmitriy N. Andreychenko, 20, on suspicion of first-degree making a terroristic threat. Greene County Prosecutor Dan Patterson has yet to file formal charges in the case.

The Springfield Police Department arrived on scene within three minutes of the call. Police stated Andreychenko pulled up to the Walmart, where he donned body armor and military fatigues. Police say the man had tactical weapons.

Police then say Andreychenko walked into the Walmart Neighborhood Market where he grabbed a cart and began pushing it around the store. Police say the man was recording himself walking through the store via a cell phone.

The store manager at the Neighborhood Market pulled a fire alarm, urging people to escape the store.

Police say Andreychenko then made his way out an emergency exit where a former firefighter held the man at gunpoint. At that moment Springfield Police arrived on scene and detained the man.

The Springfield Police Department could not confirm the nature of statements said by the man to those inside of the Walmart, but they do confirm that the man had loaded weapons, and over one hundred rounds of ammunition.

Police also observed many shoppers hiding outside the Walmart and at nearby businesses.

Lieutenant Mike Lucas said it was clear the man's intent was to cause chaos, saying in part, "His intent was not to cause peace or comfort...He's lucky he's alive still, to be honest."
