The body is believed to Reilly Scarborough, 9. His sister, Acelynn Wester, 2, was found dead in a "heavily wooded area" near Cove, Arkansas, on Friday. Their mother, Bethany Jo Wester, 43, was found dead in a nearby creek days earlier, according to the New York Daily News.

A third relative, 66-year-old Steven Paynethe, the kids' great-uncle, also was found dead. The cause of death has not been revealed for any of three, the Daily News reported.

A man who is already in the Polk County Jail on unrelated charges reportedly helped police find the body, and now Brian Bliss Travis could face capital murder charges, the sheriff's office said, according to the Daily News.
