Firefighters, military, and members of the community walked 5 miles around the island while carrying weighted backpacks to honor the legacy of fallen Boston firefighter Bobby Kilduff Jr.

Kilduff, who was a 24-year veteran of the Boston Fire Department and a U.S. Marine Corps veteran, was killed back in May while battling a fire in Dorchester.

Sunday’s event was put on by a non-profit called Oscar Mike Ruckers, based out of Hubbardston.

According to Tom Lyon, the founder of Oscar Mike Ruckers, the heavy backpacks worn during the walk signify the fallen.

All of the proceeds from the event are going directly to the Kilduff family.
