LUSK, Wyo. (AP) — Authorities have resolved a poaching investigation in eastern Wyoming that began after local landowners reported Nebraska hunters illegally taking mule deer.

The joint investigation between the Wyoming Game and Fish Department and Nebraska Game and Parks resulted in four Nebraska residents pleading guilty to several violations and more than $17,500 in fines and restitution.

The Wyoming Game and Fish Department says the investigation began in November with surveillance.

Wildlife officials observed four people hunting in Wyoming while the season was closed, trespassing on neighboring properties, baiting deer to hunt them, chasing deer off the road with a vehicle, and spotlighting and shooting after legal hunting hours.
