CODY (WNE) — A man is facing charges in federal court for assault with a dangerous weapon and kidnapping, holding another man at knifepoint in Yellowstone National Park.

Gregory Toth is accused of assaulting a co-worker, pressing a knife against their neck and choking them at the Fishing Bridge RV Park last Friday.

If found guilty of those and other charges, Toth could face up to life in prison and $520,000 in fines.

According to court documents, the evening before the assault, the victim and another co-worker drove to Cody to go to Walmart. While at the store, Toth called the victim and accused him of sleeping with his ex-girlfriend. Toth threatened that he would come to Cody and deal with him “properly.”

Around 5:20 a.m. the next morning the victim awoke to Toth calling his cellphone, according to court documents. The victim didn’t answer but soon after heard a banging on his trailer and more phone calls from Toth. As the victim was about to open the door, Toth allegedly pushed it in and threw him to the ground. Toth put his hands around the victim’s neck and started choking him.

According to court documents, Toth searched the victim’s phone but found no evidence of contact between the two. After a few minutes Toth allegedly relented and let the victim up. Eventually Toth allowed the victim out of the trailer, which was when they ran toward a co-worker commuting to Old Faithful.
