YMMV / Suspect Zero

• I Am Not Shazam: The phrase/name "Suspect Zero" used by O'Ryan throughout the movie does not refer to himself as a Serial Killer. It refers to O'Ryan's theory of a super-competent serial killer who can move across the country killing hundreds of victims without leaving any pattern or being detected by authorities. Although as Mackelway points out once this is clarified, this doesn't rule out the possibility that O'Ryan could be Suspect Zero himself... He isn't. Suspect Zero is an ice cream courier who kidnaps children, puts them in his freezer truck, tortures them at his home, and buries them in the backyard. Between his other victims, O'Ryan spends most of the movie trying to catch him, and the faxes he sends to Mackelway are the cases of these missing children.
