WILMINGTON, Del.—The 3-year-old son of a firefighter was struck and killed in Delaware over the weekend shortly before a memorial walk was to begin to honor three firefighters killed in an a blaze seven years ago, authorities said.
The Wilmington fire chief’s office said a group of off-duty Wilmington firefighters, family members, and friends were gathering just before 10 a.m. Sunday for the walk to honor three city firefighters killed in the line of duty at a structure fire on the same day in 2016.
