The cause of a three-alarm fire in York City early Saturday morning that displaced eight people and caused $200,000 in damage to four row homes is still undetermined, said York City Fire Chief David Michaels.
Crews responded to reports of a structure fire shortly before 2 a.m. at 120 Manchester St.
Michaels said the residents of the house where the fire began had a "makeshift patio" outside the front of the house. That's where the fire started, but investigation is ongoing to determine why.
"We know the people were out there smoking, so it could have been that; it could have been set -- it very well could," Michaels said.
He said there is nothing so far to link it to a nearby fire the night before that was ruled to be arson.
The fire spread quickly from the patio up the front of the home and over to three adjoining row houses.
Two people suffered minor injuries, Michaels said. One of the residents of 120 Manchester St. was transported to York Hospital, and one firefighter was treated for minor burns at the scene, but eventually returned to fighting the flames.
The Red Cross said in a press release that it is assisting six adults and two children who the fire displaced.
