COLUMBUS (AP) - A sheriff has identified the three adults slain at a trailer home in far southern Ohio where authorities also found the body of a 7-year-old boy.

The Lawrence County sheriff shared the victims' names after a manhunt ended Friday with the arrest of 23-year-old suspect Arron Lawson, a relative who lived down the road.

Sheriff Jeffery Lawless identified the victims found Wednesday as a 28-year-old resident of the home, Stacey Jackson, and two relatives who lived at a property on the same road. They are 50-year-old Donald McGuire and 43-year-old Tammie McGuire.

The slain boy, Devin Holston, initially was the subject of a missing-child alert and was later found dead in the same trailer. Lawless says the child's body was apparently hidden.

Lawless says Lawson was unarmed and ready to give up when officers arrested him as he walked down a road in far southern Ohio. He added Lawson is an outdoorsman and hunter but seemed "worn out from being out in the elements" and didn't flee when confronted Friday.

The sheriff wouldn't disclose what Lawson said to the arresting officers.

It wasn't immediately clear whether Lawson has an attorney.

He was arrested roughly 12 miles south of the trailer home where the bodies were found.
