A 12-year-old Texas girl who shot her father and then herself in a murder plot with a friend has died, officials said on Wednesday. 

The girl died from a self-inflicted "gunshot wound of head" on September 22, two days after the shooting, according to the Tarrant County Medical Examiner’s Office.

She and her friend had plotted for weeks to murder their families and pets, the Parker County Sheriff’s Office said. The girl was planning to leave the city of Weatherford after killing her dad and drive to Lufkin to pick up her friend. The two then planned to flee together to Georgia.
