The Delaware Division of Forensic Science is now without a director.
Michael Wolf took the job 18 months ago after a scandal that rocked its crime lab.
The Wilmington News Journal reports that he quit in July and told the paper he had done so because of a lack of resources and staffing.
The division’s annual report found that the agency was struggling to keep up with homicides, rape and drug deaths.
In 2014 the lab had been hit with evidence thefts and mismanagement.
