A probable cause statement released by the Springfield Police Department outlined new details surrounding an altercation with an armed man inside a south Springfield Walmart, on Thursday, including a statement from the suspect that he wanted to see if his second amendment rights would be respected.

Dmitriy Andreychenko, 20, told investigators that he pulled into the Walmart parking lot and started to record himself with his phone. He grabbed his body armor from the trunk, along with his rifle, and put them on.

From there, Andreychenko told investigators that he grabbed a shopping cart and made his way into the store, curious to see if anyone would stop him and tell him to leave. "I wanted to know if that [sic] Walmart honored the second amendment," said Andreychenko.

Andreychenko said his intentions were to buy grocery bags, and that he didn't intend for anyone to have a negative response. He said the rifle had a loaded magazine, but no round in the chamber, and that he also had a handgun on his right hip, which was loaded with one round in the chamber.

Andreychenko said he was surprised by other customers' reactions, telling investigators, "This is Missouri. I understand if we were somewhere else, like New York or California, people would freak out." He told investigators that he put on body armor to protect himself after several recent shootings across the country.

Andreychenko said he heard the fire alarm go off while he was inside the store, and made his way to an exit. That's where he was confronted by a citizen with a gun. The man pointed the gun at Andreychenko and told him to put his hands up.

In a separate interview with Andreychenko's wife, Angelice, she told investigators Andreychenko had told her of his plan to walk into Walmart with a gun, and that she told him it was not a smart idea; that people would take him seriously due to recent mass shootings.

She told investigators that Andreychenko said he wanted to see if Walmart would respect his second amendment rights. Angelice referred to Andreychenko's actions as those of an immature boy.

Anastasia Andreychenko, the suspect's sister, said she received a call from him just after 3:00 p.m. Thursday. Andreychenko asked her if she would videotape him going into the Walmart with a gun, and that he referred to the action as a social experiment on how his second amendment right would be respected in a public area. Anastasia told him it was a bad idea, and that she did not want to help him take video.

Walmart surveillance video showed the sequence of events, including Andreychenko donning a ballistic vest and rifle, and walking through the aisles of the store while recording with his cell phone. According to the probable cause statement, the surveillance video showed other customers running away from Andreychenko while he made his way through the store.

Andreychenko currently faces charges of making a terrorist threat in the second degree. If convicted he could face up to four years in prison and up to a $10,000 fine.
