THOMPSON MESERVE’S PURCHASE, N.H. (AP) - A Monroe County man who suffered a medical emergency in the White Mountains of New Hampshire has died despite extensive efforts by rescue crews, authorities said.

Jason Apreku, 21, of Stroudsburg was hiking with friends Friday when he collapsed on Mount Madison, the New Hampshire Fish and Game Department said in a statement.

His friends called for help and began CPR while an Army National Guard helicopter was dispatched from Concord.

Severe wind kept the helicopter from reaching the hiker, however, and he later died, according to the department.

Crews carried his body to a hut in below-freezing temperatures, and a helicopter brought him and the rescuers off the mountain Saturday morning.
