Police are searching across two states for a woman who allegedly set her sister on fire in Temple, Texas, and fled the scene.

When responding to a report of a domestic disturbance and a burn victim Saturday afternoon, Temple police found a woman whose body was covered in life-threatening burns. She was rushed to the hospital.

The woman had been involved in a dispute with a family member, according to police. The dispute became violent and the victim's sister doused her with gasoline and lit her on fire, police said.

The suspect was identified as 31-year-old Iaisha White, who fled the scene in a gray or silver Dodge Stratus 4-door, police said. Officers searched the area, but could not locate her. White is wanted on a charge of aggravated assault.

Police say White was spotted at a 7-Eleven store in Moore, Okla., on Saturday evening.
