He killed them by bashing them over their heads with a stone. The police have brought in a number of suspects but have not been able to charge anyone with the murders.
6. Frankford Slasher
Between 1985 and 1990, at least eight people were stabbed to death in Frankford, Philadelphia by a serial killer known as the Frankford Slasher. A local man named Leonard Christopher became a suspect in one of the murders; he was later jailed for it, but some of the victims were discovered after Christopher was put behind bars, which means the Frankford Slasher is still on the loose.
