Athens, Georgia, is home to the University of Georgia, and the police there are used to college town-type crimes: break-ins, bar fights and assorted rowdiness. That kind of thing.

But the 911 call that came in on the night of March 13, 2019, was unlike anything the Athens-Clarke County Police Department had ever encountered.

On the phone was 28-year-old Jimmy Zhong, a local party boy and Georgia alum who frequented Athens’ drinking establishments. He wasn’t like the other town rowdies – Zhong was also a computer expert who had an unusually robust digital home surveillance system.
