A former Alabama sheriff’s deputy has been indicted on federal charges in an on-duty sexual assault and kidnapping.

The U.S. Department of Justice on Friday announced the charges against 32-year-old Joshua Matthew Davidson. He formerly worked for the Dallas County Sheriff’s Office.

Davidson is charged federally with deprivation of rights under color of law, kidnapping and witness tampering.

According to the federal indictment, on Jan. 30, 2020, Davidson, while on duty, kidnapped and sexually assaulted a woman in his custody. The incident reportedly happened during a traffic stop in Selma.

Records indicate Davidson used a deadly weapon during the kidnapping and aggravated sexual assault, which included forcing the victim to perform oral sex on him.

Davidson is also charged with making a misleading statement to investigators regarding his conduct related to the sexual assault and kidnapping. That charge involves statements made to Alabama Law Enforcement Agency investigators.

The FBI Mobile Field Office investigated the case. The indictment was announced by Assistant Attorney General Kristen Clarke of Justice Department’s Civil Rights Division, U.S. Attorney Sean P. Costello for the Southern District of Alabama and Special Agent in Charge Paul W. Brown for the FBI Mobile Field Office.

Davidson pleaded not guilty during arraignment this week. A trial is tentatively set for December.

If convicted, he faces the possibility of life in prison.

Davidson was also arrested on state charges involving the same incident in 2020. He resigned after his arrest.

He was indicted in Dallas County on those state charges – first-degree sodomy, first-degree human trafficking and second-degree kidnapping – in June of this year.

His trial on the state charges is set for May.
