Flames tore through homes overnight in South Jersey causing a partial collapse.
Fire broke out around 4 a.m. at a corner property at S 4th and Spruce Streets in Camden, New Jersey.
Original reports had one person suffering from smoke inhalation, that report wasn't confirmed by firefighters.
The fire quickly spread to two alarms and engulfed two abandoned row homes despite on-and off rain falling and firefighting efforts. Firefighters stood on top of a third home trying to contain the flames.
As NBC10 cameras rolled part of the building collapsed -- bricks striking one firefighter as he tried to get out of the way. The firefighter is expected to be OK.
Firefighters said it's possible that squatters in the 100-year-old homes could have caused the blaze but that an investigation will determine the exact cause.
