TWISP, Wash. -

Okanogan County authorities believe they have located the remains of a man missing since June 2012 near Twisp.

On April 21, Twisp Police Chief Paul Budrow received a call from his family that their dog had brought home a human skull. He went home along with two Okanogan County sheriff's deputies and, after a four hour search along the river near his home, located human remains four miles south of Twisp 100 yards away from the Methow River.

Evidence found at the scene has lead authorities to believe they have located Nicholas Tortora, 21, of Twisp, who was reported missing by his family on June 3, 2012. At the time he went missing his family said he was despondent and they weren't sure what he was going to do.

A subsequent search of the area included a cell phone trace, which indicated that he had been in the Twisp area approximately five miles northwest of where his remains were found Monday. Because they weren't sure where he was in the area, the search was eventually called off and he was declared a missing person.

The remains found Monday were approximately a half mile south of his residence. There were no signs of foul play found where the remains were located.

Tortora's family was notified Monday about the discovery, but confirmation is pending positive identification of the remains.
