ANCHORAGE, Alaska (AP) — A Colorado man who worked as an Alaska master hunting guide has been sentenced to 30 days in jail and fined $35,000 for hunting violations.

Alaska State Troopers say Thomas Shankster of Aurora pleaded guilty Monday in Aniak (ANN-ee-ak) to two counts of aiding in the commission of a violation and two counts of failure to report violations. Four charges were dropped as part of a plea agreement.

Shankster was sentenced to 600 days in jail with 570 suspended.

Wildlife troopers in McGrath began investigating Shankster and his business, Alaska Trophy Hunts, in fall 2014.

Troopers say he wasted moose or caribou five times, twice failed to report violations by his assistant and falsified a record claiming game meat had been salvaged.

Nine wildlife troopers spent nearly 1,000 hours investigating.
