AURORA, Colo. -- A man fatally shot in a dispute over a parking space was an assistant principal for Aurora Public Schools and a former football player at the University of Colorado who was drafted by the Seattle Seahawks.

Arapahoe County sheriff's office spokeswoman Deborah Sherman said 46-year-old Anthony "T.J." Cunningham died Monday.

Authorities said 31-year-old Marcus Johnson is being held on a first-degree murder charge. They said Johnson shot Cunningham on Sunday in a parking lot between two schools.

Hinkley High School's website lists Cunningham as an assistant principal.

Cunningham was a receiver and defensive back in college. He was a member of the Seahawks in 1996 before injuries ended his playing career.

University of Colorado athletic director Rick George said Cunningham was an active alum and that his death is a tragic loss.
