A grandmother and grandson were killed and the teen's father was seriously injured when a fire swept through a house early Sunday morning in Quincy, Massachusetts.
Fire officials said the blaze broke out at 1:24 a.m. at a home on Bell Street and quickly reached two alarms.
Officials say the father jumped out of the house and tried to get back in to rescue his 19-year-old son, identified as William Powers and the 67-year-old grandmother, identified as Thelma Powers but was unable to do so.
Firefighters also tried to rescue the two inside the home, but were ordered out because of the dangerous conditions.
The fire was extinguished within an hour but authorities said a man and a woman were found dead inside the home. Their identities have not yet been released.
The father was taken to an area hospital with burns and smoke inhalation.
The cause of the fire is under investigation.
