A former Bureau of Land Management (BLM) employee faces multiple charges in connection with the fatal shooting of three horses located in a federal corral in Rock Springs, Wyo., in June.

The two domestic horses owned by BLM wranglers and one wild mustang were discovered dead in the corral on June 12 when a BLM employee arrived to feed them.

Yellowstone County Sheriff’s deputies and BLM law enforcement officers arrested Jason Hein, 39, in Billings, Mont. on Sept. 24. He is charged with three counts of felony aggravated cruelty to animals, one count of misdemeanor unlawful killing of wild horses, and three counts of property destruction and defacement. Hein was a BLM maintenance employee at the time of the incident.

If convicted, he faces penalties of up to two years in prison and fines up to $5,000 for each animal cruelty charge, up to six months in prison and fines up to $750 for the wild horse killing charge, and up to 10 years in prison and fines up to $10,000 on the property charges
