A Mancos, Colo., hunter was placed on three years probation in U.S. District Court Friday for illegally killing a desert bighorn sheep seven years ago in Nevada.

Barrett Wynn, 30, was convicted in January of a misdemeanor charge of killing the sheep on a tag drawn by a Nevada woman.The sheep was killed in December 1982 in the Muddy Mountain Range near Lake Mead, 30 miles southeast of Las Vegas.

Wynn had faced a maximum penalty of one year in jail and a $10,000 fine.

The violation was discovered when fish and game officials conducted a routine inspection of a taxidermist studio in McCammon, Idaho, in 1987 and found the sheep's horns.

The taxidermist told authorities he got the horns from Wynn, but further investigation revealed the sheep was killed on a tag issued to a Nevada woman, said Assistant U.S. Attorney Anne Perry.

According to law, the person who draws the tag must kill the animal, she said.

Wynn also faces charges in Utah where he is accused of leading an Indiana man on an illegal trophy deer hunt. Authorities have accused the pair of killing a buck out of season with no permits, then taking only the head.
