chunk: Smith attempts to shoot Brooks, but Brooks reveals that, at some point prior, he had broken into Smith's apartment and bent the firing pin on Smith's pistol, rendering it inoperable on the off-chance that Brooks would change his mind. Brooks' brush with death makes him realize he wants to live to see his grandchild, and he turns on his would-be murderer, slitting Smith's throat with a shovel and hiding his body in the open grave. With Smith's urine providing the only DNA evidence of the Thumbprint Killer at a murder scene, Brooks will remain undetected. Smith is named as the Thumbprint Killer and Brooks returns to his normal life.
