Jesse Farber of Tamaqua vanished one week ago today.

Countless hours of searching by experts, volunteers, helicopters and K-9 units have failed to produce a clue as to what happened to the 29-year-old father of two.On Sunday, Farber's brother, Jonathan, and cousin searched some of the more elusive spots along Sharp Mountain where a man might get lost."Corey Fritz and Jonathan searched the crevasses," said Rae "Sweetie" Ferryman Monday morning as she sat on the rear patio of her New England Valley home.Ferryman is Farber's grandmother, and the two were very close.Ferryman and husband Patrick own land that stretches to the bottom of Sharp Mountain, and there's speculation Farber was trying to reach them via a mountain path last Tuesday when something went awry.There also are reports of Farber having been seen late Aug. 11 walking along Valley Road toward Tamaqua.Five days of an all-out effort and countless hours of intensive mountain work by hundreds have failed to find an answer.Speculation abounds as to what might have happened."I don't think he's on that mountain," said searcher Joe Shamonsky of Hometown. Shamonsky believes there's a chance Farber was actually on Locust Mountain on the opposite side of town when he placed the phone call.Still, Shamonsky turned up at Sharp Mountain to do what he could to help.As a father and former firefighter, Shamonsky understands the heartache a parent endures when a child is missing or possibly hurt.That empathy stirred him to offer his assistance at the base camp over the weekend.Shamonsky enlisted the aid of grandson Devon Moerder, 18, and his girlfriend Alexis Hird of Wind Gap.The couple spent a hot, muggy Sunday using Shamonsky's four-wheeler to penetrate places that might've been overlooked."We went across from Newkirk," said Moerder, where there's a mini lake. And I checked that old dynamite place and then went to the New England Valley side."Shamonsky even called Verizon to inquire about cellphone towers and phone signals.The official search for Farber ended 5:30 p.m. Saturday and officials don't intend to relaunch the search unless additional evidence or information surfaces to help pinpoint a locale.As of right now, the search for Jesse Farber, 29, of Tamaqua, drew more than 100 hikers, ATV riders, a Pennsylvania State Police helicopter, a Pennsylvania National Guard military helicopter, multiple search-and-rescue experts and highly trained K-9 units.Family and friends continue to check the mountain on a daily basis.On Monday morning, a black bear was seen walking on all fours along the S-curves close to where Valley Road meets with Lower Road, perhaps rousted by intensive searching of the woods over the past week.It was a week ago this evening when Farber phoned his girlfriend in great distress. He reportedly indicated his position as the woods to the rear of the school, and that his phone battery was dying and he was in need of help.Those who know him said the school would be Tamaqua Area High School because Farber is very familiar with Sharp Mountain. Others said, at least initially, he could've meant Tamaqua Elementary School, in which case his location would have been Locust Mountain.The brief cellphone call was the last contact anyone has had with him.The family urges anyone with information to contact the Tamaqua Police Department at 570-668-5000.Those who wish to remain anonymous are encouraged to step forward and their anonymity will be respected.
