Police say a fire that killed four people at a Lehigh County apartment house doesn't appear suspicious, but the cause remains unknown.
The fire broke out Sunday afternoon in Emmaus, about 60 miles northwest of Philadelphia.
The Express-Times of Easton reports police said Wednesday that investigators have determined the fire was not suspicious and that there was no evidence of criminal activity. The cause of the blaze is still being sought.
The Lehigh County coroner said the bodies of 48-year-old Melissa Twining, 16-year-old Montana Twining, 56-year-old Lena Marie Adamo and 65-year-old David Jenkins Jr. were found inside. The coroner says they all died of thermal injuries and smoke inhalation.
The building had been a funeral home until the 1960s or 1970s, when it was converted into apartments.
