The search for a missing Staunton man continues on Shenandoah Mountain in Augusta County.
Augusta County Sheriff Randy Fisher says crews are concentrating on an area where a search dog had multiple alerts on Sunday.
Fisher says the terrain is steep and treacherous.
Augusta County's Sheriff's Office held a news conference Monday to provide an update on the search for 60-year-old Robert Fitzgerald.
Fitzgerald was last seen on Nov. 12. He was reported missing Thursday when he didn't show up for work.
Fitzgerald's vehicle was found near the Confederate Breastworks Trail. Police say he dropped his cell phone in that area while hiking on Nov. 11 and returned the next day to find it.
Searchers haven't found any signs of Fitzgerald since the search began Thursday.
However, his cell phone was found the day after he went to search for it.
If the dogs pick up another scent on Monday, search crews will go shoulder to shoulder through the area. However, they will most likely call the search off if they do not find any new evidence after Monday.
