Police said store employees suspected Steen and another person were shoplifting vehicle maintenance fluid from the store, so they confronted them.
The situation turned violent, with the employees reportedly overpowering the two men and holding them down outside the store, WDAF-TV reported.

The strangulation took place outside of the auto parts store.
Authorities said Steen’s death was ruled a homicide caused by strangulation. In a press conference, Wyandotte County District Attorney Mark Dupree said Steen’s “airway was completely stopped,” WDAF-TV reported.
The second individual was hospitalized with minor injuries, police said.

The suspect reportedly confessed to hitting the two victims with his truck after an argument over money.
During the press conference, Dupree announced a second-degree murder charge against 39-year-old Carl Kemppainen, the manager of the auto parts store, in connection with the death of the alleged shoplifter.
Dupree also urged the public to not take justice into their own hands, saying, “Make no mistake, it is law enforcement’s job to do the policing, no one else’s,” according to WDAF-TV.
