A Casper man has changed his plea on charges stemming from a stabbing in a drug deal gone bad.

Thirty-four year old Justin Glidden entered a no-contest plea to one charge of aiding and abetting with an aggravated assault.

Prosecutors say Glidden helped attack and stab Lester Brown Junior in February, after Brown had shorted several people on a drug deal.

In exchange for his plea, the state will seek no more than a one and one-half to three year prison sentence.

Glidden is free on twenty-five thousand dollars bond, and will be sentenced at a later date.
