ARAPAHOE COUNTY, Colo.

Johnson, 31, has a criminal history that includes assault and a weapons possession charge. He appeared in Arapahoe County Court on Tuesday morning for the advisement that lasted about 20 minutes. Johnson didn’t speak much, only whispering to his attorney.

According to court documents, Johnson and Cunningham lived across the street from each other and had an ongoing dispute over a parking space. The men went to Eaglecrest High School so they could “box it out.” That situation quickly escalated from yelling and name calling to the shooting, where Cunningham was fatally injured.

“I expect him to remain in place,” said 18th Judical District Attorney George Brauchler of Johnson, “There isn’t any amount of money on the planet Earth at this moment that could get him out of custody.”

Cunningham played cornerback and wide receiver at the University of Colorado from 1992 to 1995. He also went on to have a short professional career in the NFL with the Seattle Seahawks. He was Hinkley High School’s assistant principal.

Neighbors told CBS4 that it was out of character for Cunningham to be involved in a dispute in the first place.
