Officials are crediting OnStar with helping Harrison County Deputies tracking down the stolen pickup Sunday driven by Mytrez Woolen. He’s the man accused of fatally shooting Starrville Methodist Church Pastor Mark McWilliams inside the church in Winona. OnStar located the vehicle, and while the pursuit was ongoing, ONSTAR disabled the pickup. General Motors says once OnStar shuts a car down, it is impossible to restart. Woolen faces Capital Murder with other charges, and his bond is $3.5 million.
