DELPHI, Ind. (AP) — Indiana conservation officers are seeking the public’s help in their ongoing search for a 4-year-old boy swept away by high waters in May.

Owen Jones is presumed dead after getting caught in Deer Creek’s rain-swollen current on May 23 during a family outing at a park in Delphi, about 60 miles northwest of Indianapolis.

Conservation officer Lt. Dan Dulin tells the Journal & Courier he’s urging people using Deer Creek and the Wabash River, about three miles (5 kilometers) downstream, to look for signs of the Monticello (mahn-tuh-SEL’-oh) boy and to report anything they see to police.

Months of searches along both waterways have proved fruitless. A portion of Deer Creek was dammed last week, but a search of log jams there found no sign of the boy.
