PARKER COUNTY, Texas — A 12-year-old girl is suspected of shooting her father and then herself in a murder plot, according to Parker County Sheriff’s Criminal Investigations Division.

The incident took place on Sept. 20 around 11:30 p.m. at a home in northwest Parker County, which is located just west of Fort Worth. Sheriff’s deputies located the girl from Weatherford in the street with a gunshot wound to her head, and then found her 38-year-old father with a gunshot wound to the abdomen inside the family’s residence.

The two victims were transported to a hospital via air ambulance. Investigators believe the 12-year-old girl shot her father, fled the scene and then shot herself. They found a handgun underneath her.

CID members discovered the girl had planned for several weeks to kill her family and pets. She was in communication with another girl from Lufkin, Texas, who was also plotting to kill her father, but ultimately did not carry through with the plan. The two of them had planned for the Weatherford juvenile to drive to Lufkin to pick up the other girl and for them to escape to Georgia together. Lufkin Police are also investigating this incidence. They have charged the Lufkin juvenile with criminal conspiracy in the planning of a murder plot.

The adult’s name has not been released in order to protect the identities of the minors.

“Due to the injuries, the age of the juveniles and the sensitive case matter, information released regarding this case will be limited,” said Parker County Sheriff Russ Authier.

This is an active investigation.
