Governor Maura Healey has ordered flags in Massachusetts lowered to half-staff in honor of a fallen firefighter. 

Robert Kilduff died in the line of duty at the scene of a triple-decker fire in Boston's Dorchester neighborhood Saturday night. 

The governor said his death is "heartbreaking" and "a reminder of the dangers firefighters face everyday." 

Flags will remain at half-staff through the day of Kilduff's funeral.
