Authorities are trying to pinpoint the cause of a massive fire that displaced some Brockton residents over the weekend.
The blaze at a multi-family home at 312 N. Main St. broke out Saturday afternoon.
Though no one was hurt, authorities say one woman had to be taken off a fire escape by a ladder crew.
The fire started in a unit on the first floor, possibly because of a faulty light fixture.
At least two of the apartments are uninhabitable.
