"Our hearts go out to the victim's family and loved ones," Lynn Fire Chief Daniel Sullivan said in the statement. "On behalf of the Lynn Fire Department, I want to extend our heartfelt condolences for their loss."

Firefighters brought the blaze under control within an hour of responding, officials said. The cause of the blaze is still under investigation.

Officials said that no other injuries were reported, though several residents of the six-family apartment building have been displaced due to smoke and water damage.

"As sad as this incident is, working smoke alarms alerted other residents to the danger and may have prevented an even greater tragedy," Chief Sullivan said in the statement.

There have been 40 residential fire deaths in Massachusetts this year, officials said in the statement.

Investigators determined that smoke alarms were present and operated in just 14 of these cases; they were either not present, not working, or their performance could not be determined in the remainder, authorities said.
