SOUTH SACRAMENTO -- Four people, including one Sacramento Metropolitan Fire District firefighter, are recovering after a fire ripped through a group home overnight in South Sacramento.
A video shows flames engulfing a Jenna Way home early Sunday morning.
Cathy Calmes lives next door and was getting ready for bed when the fire broke out.
"Then I heard a pop sound and then I just started hearing people yelling," Calmes said.
Metro Fire spokesman Chris Vestal says firefighters responded to the fire around 3:30 a.m.
"We learned there were possibly residents inside," Vestal told FOX40.
"I believe there were seven people," Calmes said. "I don’t know them all, but there was like three or four elderly men living there."
Vestal said three of those people living in the home suffered injuries. A firefighter was also taken to the hospital. Fire officials say the people taken to the hospital are expected to be OK.
"(The firefighter) received some minor burns to his flank area. He fell through the roof up to about his waist and was able to self-extricate with the help of his partner," Vestal said.
Four additional people have been displaced and are currently being assisted by the American Red Cross, according to Metro Fire.
Edmond Jones said he used to the own the house. He came by as soon as he heard the place he once called home for 30 years was a total loss.
"I was shocked," Jones said. "It’s sad because it’s a memory. We live for memories."
Vestal said officials may know what caused the fire.
"The fire began in one of the back rear bedrooms and it began on the bed," Vestal said.
They are looking into the possibility the fire may have started from a lit cigarette.
"Some of the other residents report that the person who resided in that room was a smoker," Vestal told FOX40. "So we’re looking into whether he may have had some cigarettes he did not extinguish all the way."
