The St. Louis County coroner is trying to determine if police shot an Affton man to death, or if he shot himself.
St. Louis County Police were called to a home in the 9800 block of Arv-Ellen about 7:30 Saturday night because of a man reportedly waving a gun around in his front yard and yelling for someone to call police.
Officers arrived to find 36 year old Shawn Spiros sitting on the front porch.
Police say they tried to talk with Spiros, but he pulled a gun from his waistband, raised it toward officers and then at his own head. Police spokesman Randy Vaughn says it appears that Spiros and an officer fired at the same time. It's yet not clear which shot killed Spiros. The coroner is expected to release a report on Monday.
