A $1,000 reward is being offered for information on the illegal killing of an adult doe that was pregnant with twin fawns and found Friday in St. Albans, state wildlife officials said.

Authorities believe the deer was shot and killed about 9 a.m. Friday in a field near the intersection of Corinna Road and Nokomis Road in St. Albans, according to a news release Wednesday from Department of Inland Fisheries and Wildlife spokesman Cpl. John MacDonald.

The doe was collared and was part of the Maine Department of Inland Fisheries and Wildlife winter severity study of white-tailed deer. Department deer biologist Kyle Ravana received the mortality reading from the GPS tracking collar early Saturday morning, according to MacDonald.

Ravana performed a necropsy in the field on the doe and determined that it was pregnant with twin fawns, which would have been born in the spring or early summer of 2016, according to the release.

Ravana said the cause of death was a single gunshot wound, and he notified the Maine Warden Service of his findings.

Maine Operation Game Thief has offered to pay up to $1,000 to anyone who comes forward with information that results in a conviction the person responsible for the shooting. Maine game wardens asked anyone with information to call the Augusta Public Safety Dispatch center at 624-7076.
