The boys' family is from Zanesville and had been camping near a dam at Muskingum River State Park, about 50 miles east of Columbus.
Muskingum County officials say the family awoke Saturday morning and realized 2-year-old Anthony Joseph Tullius and 3-year-old Ayden Leroy Cecil were gone. Searchers found the older boy's body hours later about a mile south of the spillway at the dam.
Sheriff's Capt. Jeff LeCocq tells The Columbus Dispatch newspaper police dogs tracked the scent of both boys to the water's edge. Searchers used boats and planes to look for the missing toddler in the river but stopped Saturday night when the water became dangerous.
