Steven Brian Pennell: The Route 40 Killer

Background

Steven Brian Pennell, also known as "The Route 40 Killer," was Delaware's only known serial killer in modern history. Born on November 22, 1957, in Glasgow, Delaware, Pennell was an electrician by trade and a seemingly normal family man. However, between 1987 and 1988, he committed a series of brutal murders that shocked the community.

Crimes

Pennell's crimes were characterized by extreme violence and sadistic torture. He primarily targeted women, abducting them from U.S. Route 40 and subjecting them to horrific abuse before killing them.

  • Catherine DiMauro: On June 28, 1988, 31-year-old Catherine DiMauro was found naked at a construction site. She had been killed by hammer blows and strangulation, and her body was covered in blue fibers.
