November 22, 1957 - Steven Brian Pennell
Delaware's only known modern serial killer, Pennell targeted vulnerable women along a stretch of U.S. Route 40 in New Castle County, leaving investigators with a case that drew on emerging forensic techniques to secure conviction. The evidence connecting him to the murders — including fiber transfers and tool marks — made his prosecution a notable example of forensic science applied to serial homicide cases in the late 1980s.
