The plea agreement between the Brazos County district attorney’s office and 30 year old Robert McCullough Junior of Brenham has a five year prison sentence and no right to appeal the punishment or a robbery conviction. The other man, 34 year old Rufus Lockett of Houston, pleaded guilty to capital murder last year and was sentenced to life in prison for killing a clerk at the Valero store on Rock Prairie by the freeway on December 16, 2018.
