A.J. Roop is leaving his role as the Delaware Department of Justice's state prosecutor to serve as the department's new chief of staff, Attorney General Kathy Jennings announced Tuesday among other staffing changes.

The move follows the December departure of former chief of staff Rob Coupe, who has since joined the Delaware Department of Technology & Information.

"Rob Coupe and his predecessor, Greg Patterson, were phenomenal chiefs of staff whom anyone would be hard-pressed to succeed," Jennings said. "Luckily, we have A.J. Roop, a proven leader in our office who has agreed to take on a big job after serving as the bedrock of the Criminal Division for four years."

Roop was the state prosecutor for seven years. He previously led the Crime Strategies Unit, now known as the Community Engagement Unit, and worked as a criminal defense attorney in private practice. He earned his law degree from the Delaware Law School at Widener University and is a graduate of the University of Delaware.

Roop is succeeded as state prosecutor by Dan Logan, who was a prosecutor for the DOJ from 2007 to 2016, when he joined the U.S. Attorney's Office. Logan was also a former unit head for the Crime Strategies Unit, moving up from a position as an assistant attorney general. He graduated from Louisiana State School of Law, the University of Tennessee and the Salesianum School.

Several other DOJ employees have been appointed to new positions also announced Tuesday. Patty Davis is set to be state solicitor for the Civil Division, replacing Aaron Goldstein, now counsel for the Department of State.

Abby Rodgers, who has led the Family Division for the past six years and been with the DOJ for 16 years in total, has been named New Castle County's chief prosecutor. She is known for her involvement in the passage of Delaware's first human trafficking laws and the formation of the Human Trafficking Unit.

Succeeding Rodgers is Sara Reedy, acting director of the Family Division and assistant director of the Juvenile Delinquency and Truancy Unit. Reedy earlier also worked in the Criminal Division and has nine years of field work experience with the Division of Family Services, where she worked while obtaining her master's degree and J.D.

"We've been spoiled with an incredibly talented and qualified leadership team from day one," Jennings said. "Staff talent is the DOJ's greatest asset, and the fact that we're able to retain, regain, and promote incredible leaders like A.J., Dan, Patty, Abby and Sara is a boon to our department and the entire state."
