The lawsuit alleges Fall River's Gabriel House didn't have emergency response procedures in place leading up to last week’s fatal fire.

Resident Steven Oldrid alleged that he was “trapped in his room, suffered smoke inhalation, respiratory distress, and loss of consciousness” during the July 13 blaze.

The exact cause of the fire at the Gabriel House assisted living facility in Fall River may never be known, but investigators have narrowed the cause down to two possibilities, officials announced Tuesday afternoon.
