Police say a 911 call came in from a house in the 3300 block of Birdier Street about 4:30 a.m. Witnesses saw flames leaping from the two-story home.
Jacksonville Fire-Rescue crews say the top floor of the home collapsed to the bottom floor.
Firefighters say they found the victim at the bottom of the stairs of the two-story house. Police say it appeared she was trying to get out and succumbed to smoke or flames.
Police wouldn't confirm the identity of the victim, who was badly burned, but a woman told Channel 4 it was her 86-year-old mother, Margarine Cobb.
Cobb was well-known in the area, according to her daughter. She spent time volunteering at area nursing homes. She also raised eight daughters at that home but recently lived alone.
The Jacksonville Sheriff's Office sent a homicide team to investigate. The state fire marshal was on scene to investigate what started the blaze.
Margarine Cobb"She was a very Christian lady," said her daughter, Mildred Chambers. "She taught us very well about the Lord,so it makes it, for me, a little easier to accept."
