Attorneys from the Delaware Department of Justice on Friday asked a federal judge to dismiss the remaining claims in a prisoner lawsuit accusing state officials of abuses in the wake of last year’s deadly uprising at James T. Vaughn Correctional Center.

The filing came in response to inmate Donald Parkell’s latest—and likely final—attempt to hold two JTVCC wardens and commissioners of the Delaware Department of Corrections responsible for the aftermath of the February 2017 incident, which left one corrections officer dead and two others injured.
