Investigators: No cause determined in fire that killed 4

January 4, 2016

LYNN, Mass. (AP) — Authorities investigating a fire that killed four people at a multifamily home in a Boston suburb in December have ended the investigation without determining what caused the blaze.

Fire officials said Monday they couldn’t rule out arson, smoking or electrical failure as possible causes of the fire. Fire investigation standards require that a cause be left undetermined if a most probable cause isn’t found.

Investigators believe there were no working smoke alarms in the building’s front hallway.

The fire started in the front stairwell of the three-unit home in Lynn on Dec. 4. Firefighters made dramatic rescues and saved two people, but couldn’t get to the four victims.

A pregnant woman, Sonia Cruz, was killed in the fire along with her sister Maritza, niece Yasmin and nephew Rodolfo Mercedes.
