A search for a Massachusetts man missing since March 10 has led investigators to look for clues on Mount Washington trails in New Hampshire, but so far, none have turned up.

Officials say information on the whereabouts of Porith Stephon Sou, 21, of Dracut, Massachusetts, remained unknown until his vehicle was found parked at Pinkham Notch Visitor Center at the mountain on Saturday.

Searchers received information that Sou might have been seen hiking in the Cutler River drainage on Friday and most recently on the Mount Washington Auto Road on Saturday. Searchers combed the area searching for any signs of Sou.

Officials said 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 additional information.
