Federal charges against a pair of hunters in the killing of more than a dozen walrus near the Northwest Alaska village of Brevig Mission mark the completion of a two-year investigation, a prosecutor said Friday.

Timmy Henry faces one count of wasteful subsistence taking of marine mammals in the May 7, 2016 killings of 14 walrus west of Sledge Island and south of Cape Douglas. Another man, Edward Barr, was charged with the same federal misdemeanor last month.

Both men were entitled as Alaska Natives to take marine mammals for purposes including subsistence, but federal law requires that those kills not occur in a “wasteful manner.”

Stephen Cooper, the assistant U.S. attorney who handled the case, said the defendants had been “hunting as a group” at the time of the walrus kills, which included eight adult females and six calves. An enforcement officer from the U.S. Fish and Wildlife Service investigated the case.

“He had received a report from someone who had witnessed this that there were 14 dead animals, and five of the heads of the dead animals had been removed,” Cooper said. “No attempt (was) made to salvage the carcasses of the calves or the adult dead walrus.”

A village public safety officer also helped investigate the wanton-waste incident.

Henry was the last of four defendants in the case, according to Cooper. Two other men who weren’t criminally charged, Bob Tocktoo and William Kakoona, have agreed to pay $2,280 fines in connection with the walrus kills.

“This is the end of it,” Cooper said.
