Washington County District Attorney Jason Walsh has confirmed that a third person has been arrested in the murder of a Washington woman last month. Walsh says the individual has been arrested in the drive-by shooting death of 58-year-old Kristin Barfield, but he could not release the suspect’s name. He says court paperwork has been sealed for now to protect witnesses and the integrity of the investigation. Barfield was sitting on her front porch on Ridge Avenue when she was shot and killed. Authorities have said that fifteen-year-old Tyriq Moss and thirty-year-old Brandon Allen had agreed they were going to shoot Barfield’s son, Trey Willis, but apparently missed hitting him and instead, hit Barfield.
