PINKHAM NOTCH, N.H. — A 21-year-old Dracut man has been listed as missing for eight days after hiking on the Mount Washington Auto Road March 9, according to the New Hampshire Fish and Game Department.

Porith Stephon Sou’s vehicle was located at the Pinkham Notch Visitor Center on Saturday.

He has been listed as missing since March 10.

“Due to the immense area, deep snow, and the lack of specificity as to where Sou might have gone, the search has been suspended pending any additional information,” reads a press release from the New Hampshire Fish and Game Department.

The team of searchers included Fish and Game conservation officers, U.S. Forest Service snow rangers, Mountain Rescue Services (MRS) and Androscoggin Valley Search & Rescue (AVSAR).

The Mount Washington Observatory and Mount Washington Auto Road provided logistical support to get the searchers up above the tree line.

Searchers learned that Sou might have been seen hiking in the Cutler River drainage on March 8, and most recently on the Mount Washington Auto Road on March 9. Searchers combed the trails and woodlands in these general areas searching for any signs of Sou.

“The report of a person matching Sou’s description hiking on the Mt. Washington Auto Road was the most promising lead, but a search of the area failed to turn up any clues,” reads a press release from the New Hampshire Fish and Game Department.
