CHAFFEE -- The cause of an early morning house fire that killed a Chaffee man and his two nephews Wednesday in Chaffee is under investigation by the state fire marshal.
Just before 6 a.m. Wednesday emergency crews from multiple departments in Scott County responded to an engulfed house fire on the 100 block of Black Street near downtown Chaffee, according to Chaffee Police Chief Jim Chambers.
The names of the victims -- who are ages 2, 3 and 21 -- have not been released, Chambers said.
Chaffee Fire Chief Sammy Glency said a fourth person, who is the mother of the Chaffee man and grandmother of the toddlers, was transported to Saint Francis Medical Center in Cape Girardeau and later transferred to a St. Louis hospital.
"We know the point of origin was in the back bedroom and the fire rapidly burned from the back bedroom out through the front of the house," Glency said.
The state fire marshal was called in Wednesday to the help with the investigation, Chambers said.
"We didn't have any inclination of it being arson. At this time, it's termed as undetermined," Glency said.
Chaffee Fire Department and the fire marshal were on the scene until about 1:30 p.m. Wednesday, the fire chief said.
"It's just an unfortunate incident," Glency said. "I do know there were no working smoke detectors. I can't stress enough how important having working smoke detectors can be."
