Officials says four firefighters were hurt, as two of them suffered burns while inside the home looking for anyone who might have been trapped. The firefighters are expected to be OK.

The fire is under control and firefighters are wrapping things up here after more than nearly six hours on scene but West State Street remains blocked off.

“These houses are extremely old, the wood in there is extremely dry. And some of these houses get chopped up into smaller units to allow for other residents to live in and it makes it extremely hard to get in there and get to the seat of the fire,” explains Deputy Chief Anthony Moran.

In addition to the four firefighters transported, medics took one tenant to the hospital with smoke inhalation.
