S17E05: Public Service Homicide

When Carl Mullaly is discovered murdered in his apartment, Green and Cassady learn that he had recently been profiled on HardFocus, a tabloid talk show that exposes sex offenders who are caught via the ScumWatch website. With an eight-year-old girl as the only eye witness, detectives arrest the murderer, but McCoy and Rubirosa soon learn that HardFocus is a lot more involved than they claim.
