Gail Knisley, 62, of Columbus, Ohio, was fatally shot on November 25, 2003, while a friend, Mary Cox, was driving them on Interstate 270. A bullet entered the driver’s side door, narrowly missing Cox, then struck Knisley in the chest and severed her aorta. She bled out despite immediate medical attention and died of her wound.

The shooting was one in a series later attributed to Charles McCoy Jr., who became known as the Highway Shooter. The attacks prompted a large multiagency task force in Central Ohio. McCoy was arrested on March 17, 2004, and was later sentenced to 27 years in prison for crimes that included Knisley’s murder.

Did anyone who drove or traveled on Interstate 270 that November remember seeing anything suspicious that day?
