Jason Daniel Allgood, 36, was reported missing from Haines, Alaska after a solo subsistence fishing trip on the Chilkat River on June 17, 2010. He was a U.S. Customs and Border Protection officer who told a friend and posted on Facebook about the outing. When he failed to show for his 7 a.m. shift the next morning, a search began.

Searchers found his 2005 Kia Sedona on the south side of the Chilkat River downstream of Wells Bridge and discovered his backpack next to a staked subsistence net. The pack contained his wallet, a digital camera, and tennis shoes. Footprints showed he had changed into green chest waders and waded through waist-deep water to reach the fishing spot. Only one set of tracks led to the area and none returned. Extensive searches by Alaska State Troopers, fire crews, volunteers, riverboats, and a helicopter, plus probing and grappling in the convergence zone where currents are dangerous, turned up no sign of Allgood.

His backpack, boots, and net were recovered on the riverbank, but Jason Allgood himself has not been located. Did anyone in the Chilkat River area at the time see unusual activity or floating gear that could help explain what happened?
