John Sens, the former purchasing director at the Orleans Parish Sheriff’s Office, resigned from his post at the jail late Friday afternoon, Sheriff Marlin Gusman’s spokesman said.

Sens, a deputy at the jail for the past eight years, was reassigned to a security and administrative post by Gusman last year as federal investigators descended on the sprawling jail complex to check into a raft of questionable post-Katrina contracting issues.

Sens emerged as a notable figure in the feds’ investigation, but he has not been charged with any wrongdoing. A federal grand jury investigating contracting deals at the jail has not taken taken public action, though it has issued subpoenas.

John Sens is the brother of Municipal Court Judge Paul Sens, a close family friend and political ally of Marlin Gusman.

Paul Sens cited health issues when he left his post as chief judge on the court in June.
