INDEPENDENCE, Mo. — An Independence police officer and School Resource Officer was on a grueling journey to remember a fallen brother.

Officer Jeff Nunn ran the Boston Marathon Monday in honor of fallen Independence Police Officer Blaize Madrid-Evans. Nunn ran the route wearing a special shirt that says “BlaizeOn” and finished in 2:57:14.

The Independence Police Department and Mayor Eileen Weir both encouraged Officer Nunn with messages on social media.

Madrid-Evans was just 22-year-old and had just graduated the police academy when he was killed in the line of duty on Sept. 15. Madrid-Evans and his training officer were checking a house after a report of a wanted man in the area when that suspect opened fire and killed Madrid-Evans. His training officer returned fire and killed the suspect.

Madrid-Evans was laid to rest on Sept. 24.
