CROSBYTON, Tex -- The caretaker for a 2-year-old girl reported missing a week ago has been arrested on a capital murder charge after an toddler's body was found in her West Texas home.

Authorities arrested Matilda Almaraz on Thursday after FBI investigators executed a search warrant at her home, Crosbyton Police chief Greg Parrot said.

The body of the child believed to be Leah Marie Aguirre was found in Almaraz's basement.

An autopsy is pending.

Crosbyton is about 40 miles east of Lubbock.

It was not immediately clear where Almaraz was being held or if she had an attorney.

Parrot said the investigation is ongoing and Almaraz might not be the only suspect.

A statewide Amber Alert was issued for Leah, missing since Jan. 3, on Tuesday. The alert was cancelled Thursday.Body of Amber Alert Child Found
