Matthew Isbell, 24, of Marquette Heights pleaded guilty to second-degree murder Monday for his role in the 2017 murder of his friend’s mother whose body was found near the Sugar Grove Nature Center.
Prosecutors claimed that Isbell knew that, Christine Roush, 22, of Washington planned to kill her mother, Teresa Poehlman, when he drove them all in his truck to Funks Grove during Fourth of July weekend in 2017.
Roush stabbed Poehlman to death. Roush and Isbell consorted to conceal the murder.
Roush pleaded guilty to first-degree murder a few months after her arrest.
Isbell was sentenced to 12 years in prison. In exchange first-degree murder charges were dismissed.
