WELLSTON, MO (KTVI) - A wheelchair-bound man is a person of interest in a shooting that happened Wednesday morning in Wellston. By the time police arrived at the scene, he had already rolled away.

The shooting happened around 11:40, at the intersection of Wellston Place and Rock Brook. According to St. Louis County Police, two men were having an argument, when one man pulled out a handgun, and shot the victim multiple times. The victim was transported to the hospital, and at latest check, he’s in serious but stable condition.

After the shooting, witnesses spotted a wheelchair, abandoned in some bushes on Wellston Avenue, just two blocks from the crime scene. Sources say this person of interest left his wheelchair there, and was picked up by some friends in their car. That wheelchair has since been picked up by police.

How did the person of interest have time to get away? According to Wellston Police, no one called to inform them about the shooting until they were already at the scene. Officers just happened to spot the victim along their patrol route.

St. Louis County Police Officer Brian Schellman says, “We have some leads, but again, we can’t pinpoint any one person until we speak with the victim who is currently at the hospital, so we’re waiting to talk with him, and we’re trying to ascertain whether there are any witnesses to this who we haven’t come across yet.”

Sources say crime isn’t new to this person of interest; he reportedly became paralyzed from the waist down, after he was shot during a home invasion, as a juvenile.
