Update: 4 adults, 3 children dead in Lowell apartment fire
LOWELL, Mass. (AP) -- Authorities say four adults and three children have died in a fast-moving Massachusetts apartment fire, and nine others have been hospitalized with non-life-threatening injuries.
Middlesex District Attorney Marian Ryan is pledging to conduct a "long and thorough review" into Thursday morning’s fire in Lowell that had tenants jump or hand children to safety.
She says it will be a "fairly long time" before the victims are identified.
The investigation will include whether the alarm system was working and whether there were fireworks in the building, as some witnesses described hearing explosions.
Ryan says investigators have already contacted building ownership.
