BARTLETT, N.H. (AP) – A Bartlett man died Saturday after spending the night in the woods.

Tim Oliver, 51, who was an avid rock collector, stopped by a friend’s house Friday morning and then headed into the woods, said New Hampshire Fish and Game Sgt. James Juneau.

After he was reported missing this morning, Fish and Game officers led about 20 people from different agencies in a search lasting about five hours.

Oliver was found around 1:30 p.m. partially submerged in a stream about half a mile from where he entered the woods.

He was still alive at the time but died later at the hospital.

Juneau says it appears Oliver succumbed to the elements.

Temperatures dipped into the teens overnight.
