Crews battled a four-alarm fire in Stow, Massachusetts, Sunday afternoon.
Officials say that a lightning strike may have been to blame, but the official cause is still under investigation.
The blaze at 206 Hudson Road injured four firefighters, all of whom were treated at a rehab center.
At one point, crews were pulled out of the house because one firefighter was unaccounted for. The missing man was located before crews finished fighting the fire.
