A teenager died Thursday after she was injured in a Jan. 5 house fire on Iroquois Street that claimed the lives of three other people, according to Baton Rouge Fire Department spokesman Curt Monte.

Antinee Ellis, 19, was initially hospitalized after the deadly blaze in the home, at 3974 Iroquois Street, but has since died.

Gloria Anderson, 77, and her two great-grandchildren, 7-year-old Maylia Jackson and 6-year-old Michele Williams, died in the blaze. Ellis, a neighbor who was spending the night, and 6-year-old Michael Williams Jr., another of Anderson's great-grandchildren, were also initially injured, family said.

Monte said that Michael Williams Jr. is still recovering from his injuries.

Monte initially said that investigators were looking at heating systems as a potential cause of the blaze. No official ruling on the cause had been determined as of Thursday afternoon, he said.

Monte said Ellis is the 10th person to die in a fire-related death in East Baton Rouge Parish in 2018. The parish saw a rash of fatal house fires in the first month of the year when freezing temperatures gripped the Capital City.

"Our thoughts and prayers continue to be with all the families and our community," Monte said.
