According to the Tulsa Police Department (TPD), the homeowner and 47-year-old Marco Richardson had been involved in an ongoing argument that had already led to previous confrontations. Police say that on the night of the incident, Richardson, his son and three others exited two vehicles at the suspect’s house and rushed him.

While the five men had the homeowner, who has not been identified, pinned against a vehicle in the yard and were assaulting him, he drew his gun and began shooting, hitting Richardson in the chest and also hitting another of his attackers.

When police arrived at the scene they found Richardson lying in the yard surrounded by several people. He later died of his wounds at a local hospital, and the other man who was seriously wounded in the incident was transported to a nearby hospital in critical condition.

“The homeowner cooperated with officers, surrendering the pistol and providing a statement to investigators,” TPD reported in a Facebook post. “Based on witness statements and evidence collected, no charges were filed against the homeowner.”
