Joshua Knapp is guilty of murdering Iolan Shawn Cook.
Jurors took over just an hour Thursday to convict Knapp of first-degree murder, concluding the four-day trial in Allen County District Court.
Jurors agreed Knapp teamed up with Iolan Amber Boeken in slitting Cooks throat on a rural country road north of Gas. After realizing the victim was still alive, Boeken and Knapp took Cook to a desolate area of the Neosho River where they repeatedly stabbed him in the neck and left his body in the river.
