Courtney-Dean was found dead from an apparent gunshot wound to the head in a home in southwest Post, Garza County Sheriff Terry Morgan said.

The girl's mother, 34-year-old Ashlee Anne Dean, is being held at the Garza County jail on a capital murder charge, Morgan said.

No bond has been set for her yet, according to jail records.

The shooting happened about 5:30 p.m. at a residence in the 400 block of South Avenue H, Morgan said.

The girl's father was at work, and no one else was at home.

Morgan said Dean has a history of drug use and confessed to shooting her child.

"She told us she had just used," he said.

Child Protective Services returned the child to Dean in October, he said.

DPS Sgt. Bryan Witt said Texas Rangers were called in Thursday evening to assist with the investigation.

"I'm a small department and I don't have the equipment that I need to conduct the investigation as I'd like to," Morgan said.

"We called in the Rangers to make sure everything is done as perfectly as you can make it."

Witt said the Rangers will offer unique skills and tools in the investigation.
