Former Harrison County Sheriff’s Office deputy Charles “Chase” Dotson, who resigned in December 2018 amid an investigation that was launched following an official oppression complaint, turned himself in to the Harrison County Jail on Saturday morning after being indicted by a Harrison County grand jury for official oppression.The indictment was handed down earlier this week.“The indictment stems from an incident that occurred on Nov. 22, 2018, involving Dotson and Charles Collins, who was a prisoner in Dotson’s custody at the Harrison County Jail Annex,” Harrison County District Attorney Reid McCain explained in a news release. “In that incident, it is alleged that Dotson, acting under the color of his employment as a Harrison County deputy sheriff, unlawfully mistreated the prisoner by hitting him in the face and on his head.Although the prisoner did not initially file a complaint, administrators with the Harrison County Sheriff’s Office learned of the incident and immediately suspended Dotson from his duties as a deputy, the news release stated.“They later contacted the Texas Rangers who conducted an investigation,” the release continued. “Texas Ranger Josh Mason, who is stationed in Bowie County, conducted the investigation that led to Dotson’s resignation from the sheriff’s office and the case being presented to the grand jury.”Official oppression is a Class A misdemeanor that is punishable by up to one year in the county jail, or a fine not to exceed $4,000 — or both fine and confinement.A civil case against 28-year-old Dotson, filed by the alleged victim, is also pending in Marshall’s federal court.
