Summary

Franklin Andersen is found killed in Wattles Garden Park. Somebody sliced him open with a scalpel. Before Sam and Josh can finish their investigation on his case they get a new one: Carlos Ramirez, a former football star, was killed in the Old Zoo in Griffith Park. He had the same blood type like Andersen and was also killed with a scalpel. When Cheyenne Thales is found at Fern Dell Nature Trail, who was also killed with a scalpel, needed a new kidney like Andersen and shared the same blood type like the two victims before, Sam and Josh know they’re up against a serial killer, who has a specific group of people as his victims.
