Aaron Hotchner:  There have been two known copycats .
Penelope Garcia: Correct . The first _ one _ was Heriberto Seda . He killed three and wounded four in New York City . And then , there was a 14-year - old in Japan named Seito Sakakibara . He killed two other children and left the sign of the Zodiac behind .
David Rossi: The fact is the Zodiac was driven by a need for notoriety and control .
Aaron Hotchner: He enjoyed the terror he spread through the city .
