In addition to the ground search, the effort has concentrated on the fast-flowing Siletz River. Boats have searched well over 2 miles of the river surface, Spano said, and 18 divers have scoured about 1.5 miles of the river bottom downstream from the house.

A 2½-year-old boy missing since Saturday from his parents’ property along the Siletz River appears to have last been at the water’s edge before he disappeared,

The 2-year-old Siletz boy who went missing Saturday while playing in his parents’ front yard was most likely by the river bank when he disappeared, the Lincoln County Sheriff’s Office said Tuesday as the fourth day of the search for the toddler came to a close.

The primary search area has been narrowed to portions of the Siletz River, which runs up against the family’s property.

Boats and divers from the Lincoln County Sheriff’s Office and four other departments combed the Siletz River on Monday looking for a 2½-year-old boy missing since Saturday.

Hundreds of rescuers searched the Siletz area for missing toddler Dane Paulsen, using advanced search techniques.
