Thousands of people have gathered to honor a Boston firefighter who died with a colleague as they battled a fire last week.
Forty-three-year-old Walsh grew up in the Boston suburb where his father and several family members have served as firefighters.
Walsh and Firefighter Michael Kennedy were killed March 26 when they became trapped fighting a nine-alarm blaze at a brownstone apartment building in Boston's Back Bay.
Walsh lived in Boston with his wife and three young children.
His funeral Mass will be held at the Watertown church on Wednesday morning.
Kennedy's wake is scheduled Wednesday, and his funeral on Thursday in Boston.
