Also noticing the inconsistencies between the stories and the facts, Kyle extracts a confession from Rachel. She tells him that Rupert was going to leave her with nothing, so Lamar Dickie told her how to set up Rupert's death, including where to meet Kyle, but that she tried to get out of it when she fell in love with Kyle. He orders her to set up a meeting with Lamar at J.J.'s, the bar where they met. There, he confronts Dickie and points out Dickie's stupid mistakes, i.e., the compass on the dash appearing in the photos he shot of Rupert and Adele (Patricia Healy) and switching Kyle's .38 service revolver with another one Dickie then used to fire two bullets, one into the wall and the other into sand, which is the bullet he used to switch with the 9mm bullet during the autopsy. Kyle then pulls his replacement gun on Dickie and asks where his service revolver is. Dickie says that it's in his car, under the driver's seat, so they go outside. As Kyle is searching for his revolver, the police arrive, having been notified by the bartender who saw Kyle pull his gun on Dickie. Dickie yells that Kyle has a gun, and the police open fire on Kyle. Rachel, having seen everything from inside the bar, rushes to Kyle's side. Crying, she cradles him in her arms as he dies. In the final scene, Rachel picks up Kyle's gun and fires two bullets into Dickie.
