Prince Georges County police have released the cause of a deadly house fire in Glenarden, Maryland Thursday morning and the name of the victims.
Investigators say the preliminary cause of the fire on Leslie Avenue is electrical and that it was accidental.
The victims are a father and his two young daughters.
They are, 36 year old Darrell Terrance Price Jr., 8-year old Tania Monae Jeanita Price, and 4-year old Patrice Price.
An 11 year old daughter is in grave condition.
Price's 33-year wife and an 8-year old daughter, who is Tania's twin, survived.
Fire officials say they escaped the fire by going through a window.
Prince George's County Fire officials say the home had no working smoke detector on the first floor, but Prince George's County Fire and EMS fire fighter, Shawn Croissette, who was one of the first responders on the scene says the surviving 8-year old told him the family actually had a fire escape plan.
He says, "She was telling me that she was able to make it out because she had a family evacuation plan, and had family fire drills and knew how to exit the house under emergency situations."
Croissette says he not sure what happened when the fire broke out.
He says, "Only thing I can assume is because the fire spread rapidly she was in a spot where she was able to evacuate quickly where other people in her family were not able to."
Croissette says the tragedy underscores the need for everyone to take precautions.
He says, "The main lesson to be learned is have a working smoke alarms. Have a family evacuation plan. Your kids have drills at school. They do fire drills and evacuation drills. Do the same at home."
The 33-year-old mother and the 8-year-old girl remain in the hospital with smoke inhalation and other minor injuries.
Officials estimate the fire caused $100,000 dollars in damage.
