Mark Edward Harrison, 51, was shot and killed while vacuuming his red Dodge at the Star Wash car wash on the corner of Southwest 51st Street and Pennsylvania Avenue in southwest Oklahoma City on the evening of Sunday, November 25, 2012. A nearby resident walking a dog heard the gunfire; emergency responders found Harrison gravely wounded and he was pronounced dead that night at a local hospital.

Family and friends remembered him as warm, funny, and devoted to simple pleasures such as fishing, hunting for antiques, and working on old cars. Detectives canvassed the area and appealed for witnesses, noting the business’s location across from U.S. Grant High School could mean there were observers or surveillance video, but no detailed description of the shooter or a motive was released.

The person who approached Harrison and opened fire has not been publicly identified and no arrest has been announced. If anyone was near Southwest 51st and Pennsylvania that Sunday evening or has information, please come forward.
