YMMV / Diagnosis Murder S 4 E 4 X Marks The Murder

• Complete Monster: Michael Dern, aka the Casanova Killer, is a misogynistic Serial Killer who, due to his own self-pitying, has made it his mission in life to hunt down and kill women. Using his job as a gas station attendant, Michael charms women into letting him near them before murdering them. Gaining an obsession with police consultant Dr. Mark Sloan, Michael targets Sloan's friend Dr. Amanda Bentley and gleefully reveals how he plans to kill her. Michael ultimately reveals he aims to increase his victim count by two or three a day just to bask in the attention, and is happy to mock Sloan with how much his victims suffered, just to mess with him.
