SEARCH FOR MORE

The cops also decided to search one last piece of evidence, and this was the clothing on Penney on the day of the crime. They saw some sort of genetic material on her panties and slip, but unfortunately, time had destroyed what seemed like semen. All they could conclude was that semen had been ejaculated when the victim had her clothes on. That was all, until years later, they found another clue that connected to Penney’s murder.

ON THE DATABASE

In 1994, a man named Edward Grant was arrested for domestic violence. When he was questioned, police collected his fingerprints and put it on the national database, which was now available for police precincts all over. However, it took three more years for the investigators to realize that the AFIS database would be that one ally they were all waiting for.
