A Casper man accused of assaulting a man with a knife, changed his plea right before the start of his trial.

Kino Beman has entered an alford plea on one count of aggravated assault.

Police say in May 2012,  Beman attacked Tyler Johnson when he found Johnson and a woman making out.

Beman admitted that at first he lied to police about the events of that night, then said he was trying to get the knife away from the female, and that she attacked Johnson.

An alford plea is not an admission of guilt, but acknowledges that there is enough evidence for a conviction.

As part of a plea deal, prosecutors will seek no more than a two and one-half to five year prison sentence, which will be handed down at a later date.
