Overview

In July 2010, the San Bernardino County authorities were faced with one of the most bizarre crime scenes they'd ever encountered. Alerted by a concerned friend, local police arrived at the victims’ home, and the murders they discovered shook them to the ground. The crime scene showed ritualistic aspects, and quickly, one of the detectives recognized a symbol painted on the ceiling in the victims’ blood linking back to a serial killer they’d chased in 1995, before the killer seemingly took a 15-year break.
