Caleb, the son of Kyle Turner in the Netflix series "Untamed," was killed years before the main events of the show. It is revealed that Caleb was murdered by a man named Sean Sanderson, who preyed on children in Yosemite National Park. Caleb had gotten separated from his group during a park visit, and Sanderson sexually assaulted and killed him. Kyle Turner kept hallucinating conversations with Caleb as he struggled to cope with his loss. Kyle's ex-wife, Jill, later hired a park officer named Shane Maguire to kill Sanderson in retaliation, which resulted in Sanderson's disappearance. Throughout the series, Kyle wrestles with grief and guilt over Caleb's death and ultimately chooses to protect Jill's secret rather than reveal the truth. By the end of the series, Kyle tries to move on, leaving Caleb's toys behind as he departs the park, symbolizing his attempt to heal while keeping Caleb's memory alive in his heart.
