(AP) — The 6-year-old Wichita girl who was burned last week in a fire has died.

Wichita fire investigator Chris Dugan said Monday the girl died Sunday. She had been hospitalized since being burned Thursday in the fire in southeast Wichita.

The fire began when she and her two sisters – ages 7 and 4 – were alone in the home.

Fire officials say the 6-year-old used a lighter to set plastic on fire, which set her clothes on fire. Neighbors pulled the girls from the home. The 7-year-old was treated and released at a hospital. The 4-year-old was not hospitalized.

The 6-year-old had second- and third-degree burns on 40 percent of her body.

Police say the Sedgwick County District Attorney’s Office will consider possible charges against the mother.
