A dispute with a neighbor over a parking spot turned deadly on Sunday for former Colorado football standout and Seattle Seahawks player T.J. Cunningham.

Cunningham was shot multiple times in a dispute with 31-year-old Marcus Johnson on Sunday. Cunningham was immediately taken to the Parker Adventist Hospital in Parker, CO. It’s the same hospital that treated victims of the mass shooting in Aurora years back.

Sadly, Cunningham died on Monday.

“According to the sheriff’s office, the suspect told investigators that his neighbor who lives across the street from him had attacked him earlier in the day,” the Denver Post reported.

The situation escalated from an argument to a physical confrontation at the nearby Eaglecrest High School. That’s when Johnson allegedly turned the gun on Cunningham — killing the former college football star.

“He was also a good alum, an active alum and took great pride in being a Colorado Buffalo,” Colorado AD Rick George said on Monday. “Our hearts go out to TJ’s family on their tragic loss. We will miss him.”

Cunningham, 46, was an assistant principal at Aurora’s Hinkley High School. He starred for Colorado’s football team for four seasons as a wide receiver before transitioning to defensive back.

Cunningham played nine games in the NFL with the Seahawks in 1996 before injuries cut his career short.
