KANSAS CITY, Mo. (AP) — Thousands of people attended a memorial service for two Kansas City firefighters who died earlier this week when a building collapsed while they were helping to fight a fire.

Fire trucks and hundreds of firefighters from across the country lined the street in front of the Sprint Center Saturday before the service for Larry Leggio and John Mesh. The veteran firefighters died Monday when a three-story building collapsed in northeast Kansas City.

Fire Chief Paul Beradi thanked the men’s families for their sacrifice and vowed they would never be forgotten.

Leggio was a 17-year veteran and fire apparatus operator of Truck 2. Mesh was a 13-year-veteran firefighter with Pumper 10.
