Federal investigators have questioned the warden of the federal women’s prison in California and searched his office. It comes weeks after a former correctional officer at the facility was arrested on charges of sexually abusing inmates. It wasn’t immediately clear if the search at the Federal Correctional Institution at Dublin was connected to last month’s arrest. (AP Photo/Ben Margot, File)
