In May 2023, Deputy William Mosier was terminated after initiating a vehicle pursuit that crossed state lines from Dillon County, South Carolina, into Robeson County, North Carolina. During the pursuit, Mosier had an unauthorized civilian ride-along passenger in his patrol vehicle, who was not approved by a department supervisor. After the suspect’s vehicle crashed, Mosier allegedly hid the unauthorized passenger in the trunk of his patrol vehicle. These actions led to his immediate dismissal from the Marlboro County Sheriff’s Office.
