A Casper man is now admitting he threatened his ex-girlfriend with a knife.

Twenty-year old Lonnie Parham has pleaded guilty to one count of aggravated assault.

Police say in early April, they were called to the 1000 block of Saint Mary Street, where witnesses say Parham was making the threats and could see a knife in his hand.

His girlfriend recently ended a two-year relationship with him and claimed he had been physically abusive towards her.

Both Parham and his ex-girlfriend were on probation for an unrelated matter and the woman was advised to move out of their house by probation and parole.

Parham told investigators that he was at his ex’s place to get his clothes and believed she was with another man.

He said he became angry, grabbed a knife and said he was going to cut people.

As part of a plea deal, prosecutors will seek no more than a four-to-six year prison sentence.

Parham is being held on $10,000 bond and will be sentenced at a later date.
