Robert Podsner

Robert Podsner is a husband and father having secretly acted as a serial killer for decades in California. He appeared in the Numb3rs episode Disturbed. He started off with killing a girl in his high school class, Nancy Kershaw, out of jealousy over being with another man. Ever since then, he was always a proficient serial killer, with a variety of MOs, victim traits, even changing his name and moving once he felt like he was at risk of getting caught. He even killed potential witnesses to his crimes for the sake of trying to keep his anonymity and lack of detection. Charlie Eppes, after Don Epps was on leave after being stabbed, decided to look into cold cases, finally finding the connections between Podsner's murders. After additional murders, including another professor and his wife tracking Podsner, and interrupting another couple's murder, Podsner was found out, positively identified as a harasser Nancy Kershaw's boyfriend was stalked by, and eventually arrested. As he boasts it took so long to catch him and he plans and executes where serial killers can't, various souvenirs and weapons are found in his basement workshop, fully incriminating him for every last crime he committed, which guaranteed his imprisonment.
