Firefighters have found the bodies of a woman and a six-year-old girl after a four-alarm fire early Monday in a Lancaster row home.
Four people were in the home in the 200 block of East Madison Street when the fire started at around 4:30 a.m.
Two of them, a man and a 13-year-old boy, safely escaped.
Investigators said the names of the victims would be released Tuesday.
A firefighter was seriously injured while battling the blaze. Lt. Andre Kelley was transported to Lancaster General Hospital and then flown to Crozer Burn Center near Philadelphia for treatment of second-degree burns. He was listed in critical condition.
Two other firefighters, Craig Robertson and Tom Bender, were released from a hospital where they were treated for minor injuries.
The cause of the fire was not immediately determined.
