A man who led police on a car chase when he fled from an incident at a Kansas City motorcycle club has been charged with a federal firearms violation.

A U.S. grand jury returned an indictment against Casey Ellis, 25, of Kansas City, Missouri on one count of unlawful possession of a firearm after a felony conviction.

The charges stem from an incident on August 11, 2012 outside the Egyptian Cobras Motorcycle Club’s clubhouse in Kansas City, Kansas.

Police responded to the report of shots fired. Several people had been shot, including two who were killed. When police arrived they saw a man armed with a silver handgun standing over a person lying on the ground. His shirt was covered with blood.

When officers ordered him to drop the gun, he took off running. They chased him on foot until he got into a red Toyota Celica and drove away. Police followed the Toyota to mile marker 10.4 on northbound Interstate 635, where the car became disabled. They arrested Ellis at the scene.

Investigators learned that Ellis had arrived at a party armed with a .45 caliber Smith & Wesson pistol. He hid the gun outside the clubhouse before going in because he knew he would be searched before entering.

When he heard gunshots outside the clubhouse, he went outside and found his aunt lying on the ground with bullet wounds. He retrieved his gun and was holding it when officers spotted him. At the time he was prohibited from possessing a firearm because of a prior felony conviction.

He now faces up to ten years in federal prison if convicted.
