APPLETON, Wis. (AP) — Two Wisconsin officers were justified when they shot and killed a man who got in a gunfight with police that left a city firefighter dead in the crossfire last month, a prosecutor said Thursday.

Outagamie County District Attorney Melinda Tempelis said that Officer Paul Christensen and Sgt. Christopher Biese won’t face criminal charges.

Christensen and Biese exchanged shots with 47-year-old Ruben Houston of Wausau on May 15 outside of Appleton’s downtown transit center. Christensen was wounded, along with a bystander. Both have been released from the hospital.

Appleton firefighter Mitchell Lundgaard, 36, was shot and died of his injuries at a hospital.

Houston had just arrived at the transit center on a bus.
