The fire union is pushing back at the mayor and police, saying firefighters stand by what they reported after rushing into a South Boston apartment this past weekend, a matter that triggered a 51A child-neglect alert.

Sam Dillon, president of Boston Firefighters Local 718, defended the firefighters who responded to an incident involving a dead man found in an apartment where four children were present, after the mayor and police department made statements debunking details reported by the fire department and media.

“Local 718 stands squarely behind the actions taken by our firefighters,” Dillon told the Herald on Friday. “The integrity of the firefighters involved in this incident is beyond reproach. Their swift action to address what they encountered should be commended by everyone involved.”

Dillon said the incident report prepared by the Boston Fire Department is “100% accurate,” and noted that firefighters arrived prior to police officers, and therefore encountered a different scene than was described by the police department in a Thursday night statement.
