FORT DODGE (AP) - A 22-year-old Fort Dodge woman who was sexually assaulted and then critically burned when her house was set on fire has died, a hospital spokesman said Friday.

The woman, who had been hospitalized at University Hospitals in Iowa City since Jan. 8, died Thursday night, spokesman Tom Moore said.

Firefighters found her bound in the basement of her burning home. A passerby had noticed smoke coming from her house. At least two separate fires damaged the house, investigators said.

Police issued an arrest warrant for Sessions Lamont Harper, 34, of Fort Dodge.

He was arrested on Jan. 11 in Des Moines. He's currently charged with first-degree kidnapping, attempted murder, third-degree sexual assault and first-degree arson.
