A 12-year-old girl shot her father and then herself in a murder pact she made with a friend to kill their families and pets, US police have said.
Officers in Texas found the girl, who has not been named because she is a minor, with a gunshot wound to the head outside her home in Weatherford around 11.30pm on 20 September, the Parker County Sheriff's Office said.
They also found her 38-year-old father inside the house with a gunshot wound to the abdomen.
The force said the girl is believed to have shot her father, fled the scene and then shot herself.
They were taken to local hospitals by air ambulance. Their conditions are unknown.
Detectives said the suspect had allegedly planned for several weeks to murder her family and pets.
They said she had been in contact with another girl from Lufkin, Texas, to discuss the murder plot.
The other girl had also planned to murder her father but did not go through with the plan, police said.
The pair had then planned for the girl from Weatherford to drive to Lufkin, pick up the second suspect and run away together to Georgia.
The Lufkin girl has been charged with criminal conspiracy in the planning of the murder plot.
Parker County Sheriff Russ Authier said the case was in its early stages and was under active investigation.
"Due to the injuries, the age of the juveniles and the sensitive case matter, information released regarding this case will be limited," Sheriff Authier said.
