Kayla was last seen Tuesday night at a church in Bullard, 100 miles southeast of Dallas. Smith says the investigation led to the relative’s home several miles away. The body was located Saturday.

The Amber Alert for the missing 10-year-old was discontinued Saturday evening after the discovery of the body.

FBI agents had recently called for the public’s assistance in the search efforts and even offered a $60,000 reward for her return.

Smith declined to release a cause of death or a possible motive, pending charges.
