A Kingman who is representing himself in a homicide case struck a plea bargain during a hallway conversation with the prosecutor Monday morning. Mohave County superior court judge Lee Jantzen subsequently set a hearing next Monday to enter the agreement resolving the case against Polaski short of trial.

Polaski previously admitted killing his friend John Holland, 65, in late June, 2015 and burying the remains on one of Holland’s north Kingman residential properties. The remains were uncovered beneath concrete in the backyard of the Lass Avenue home in August.

Terms of the deal were not disclosed in court but were detailed during the hallway discussion. Prosecutor Jonathan Taylor told Polaski he would face a 10-18 year prison term for a second degree murder conviction.

“I’ve been guilty since day 1,” Polaski said. He also told Taylor he wanted it known that it was an act of self defense when he stabbed Holland.

Polaski also offered information in other pending criminal cases in exchange for leniency consideration at sentencing. Taylor made no promise in that regard.

The Mohave County Sheriff’s office continues investigating Polaski’s claim that he and at least one accomplice engaged in fraudulent activity to gain power of attorney to take control of Holland’s assets, including residential property and a trust account.
