Peter K. Tsorvas, an officer with the Pittsburgh Police Department, was shot on October 30, 1920, and died three days later. Nicholas Epiotis was arrested.
The shooting appears to have been linked to tensions within the Pittsburgh Greek community. Tsorvas, a plainclothes officer, and his brother were alleged to have been using their influence to extort money from Greek gambling interests that included Epiotis.
Epiotis pled guilty to voluntary manslaughter in May 1921 and was sentenced to four to eight years in prison.
