The second of two missing children has been found dead in western Arkansas.

The Polk County Sheriff's Office says the body of 10-year-old Reilly Scarbrough was found Saturday in a wooded area near Hatfield in far western Arkansas.

The discovery comes after the boy's 2-year-old sister, Acelynn Wester, was found Friday near Cove and near where the body of the children's 43-year-old mother, Bethany Jo Wester, was found Tuesday.

The woman's uncle, 66-year-old Steven Payne, was found dead Thursday in his home in Hatfield, about 4 miles north of Cove.

Suspected causes of the deaths of the four have not been released, but Sheriff Scott Sawyer told reporters that they are considered homicides and a suspect is in custody.
