SODUS, N.Y. (AP) — Authorities are continuing to search for a 14-month-old boy whose mother's body was found in western New York.

But Wayne County Sheriff Barry Virts noted Monday it would be very difficult for a child so young to sustain himself.

Virts says searchers are proceeding with the awareness that little Owen Hidalgo-Calderon might not be alive, but they hope he is.

Over 170 people combed a 350-acre (142-hectare) farm in the town of Sodus on Monday.

Owen has been missing since May 16. His 18-year-old mother, Selena Hidalgo-Calderon, was found dead Wednesday on the farm where she and her boyfriend worked.

The 25-year-old boyfriend was arrested Wednesday on evidence-tampering charges. Virts says Reyes admitted burying the mother but not killing her.

Reyes is due in court Tuesday.
