Man accused of causing fatal multi-vehicle crash faces federal weapons charge

KANSAS CITY, Mo. -- Federal prosecutors filed charges on Thursday against the man who is accused of causing a multi-vehicle crash that killed a 24-year-old Lee's Summit man Tuesday.

Keith L. Carnes, 26, now faces a federal gun possession charge. Carnes was on parole for a felony, so possessing a gun was illegal.

According to the affidavit, when officers broke the window on the vehicle Carnes was driving so they could help him, they noticed a bag of marijuana on the driver's seat and a .380 caliber semi-automatic handgun on the floorboard. Police reported that the gun had apparent blood on it and a spent shell casing was jammed in the ejection port.

The affidavit also says the 2008 maroon Pontiac G6 Carnes was driving had multiple bullet holes in the driver's side doors.

Carnes, who according to police was heading south on Prospect Avenue at a high rate of speed Tuesday night, failed to stop at the red light at 63rd Street.

When Carnes ran the red light, he hit a Dodge pickup truck that was headed west on 63rd Street. The collision pushed the pickup truck into a Nissan minivan then into a pole on the southwest corner of the intersection. Patrick Mercer, who was driving the pickup, died as a result of the crash.

Patrick had just finished rugby practice and was on the way to get dinner with his teammates.

Police say Carnes said "I have been shot, I know I have been shot," and was trying to drive himself to Research Medical Center. Emergency responders took him to the hospital where he is currently listed in critical condition. The driver of the minivan sustained only minor injuries.

Carnes has not yet been charged for his involvement in the crash, just for illegally possessing a weapon.
