The Zodiac Killer alluded police and still alludes them today when he reeked havoc on San Francisco. This cold blooded killer randomly killed without remorse or regret. Then he mocked the police during his rampage. He would send them letter in bold letters taunting them about his illusiveness and proclaimed his death toll to be 37.
This killer still baffles the police to this day though with new forensic science and salvia left on the letter he sent police are they one step closer to catching him?
