Episode 3 – The Onion Field: A Routine Stop Ends in Murder
About This Episode
In Episode 3 of Chasing the DARK, we step into one of the most haunting true crime cases in LAPD history: the 1963 Onion Field murder. On March 9, 1963, plainclothes officers Ian Campbell and Karl Hettinger made a routine traffic stop in Hollywood. The suspects—Gregory Ulas Powell and Jimmy "Youngblood" Smith—quickly turned the tables, kidnapping the officers at gunpoint and driving them over 100 miles to a remote onion field near Bakersfield. There, believing a kidnapping alone was a capital offense under California's Little Lindbergh Law, Powell executed Campbell while Hettinger escaped into the darkness. We trace the night of terror, the moral choices, the courtroom battles, and the profound psychological toll on the survivor—drawing from Joseph Wambaugh's seminal book and official records.

Episode Description
An onion field on the edge of Bakersfield becomes the final stop for a young LAPD officer whose only crime was believing in mercy. A dawn that came too late—this is not a story meant to be rushed.
March 9, 1963: Officers Ian Campbell and Karl Hettinger pull over a suspicious vehicle in Hollywood. Within moments, the two armed suspects force the officers into their car at gunpoint. Driven north through the night, the group arrives at a desolate onion field. Campbell, attempting de-escalation, is shot dead. Hettinger flees into the rows of onions, evading pursuit and eventually finding help. The killers are captured soon after, but the case exposes fractures in law enforcement support, legal misunderstandings, and the enduring scars of trauma.
In this episode of Chasing the DARK, we explore:
- The backgrounds and fateful collision of four lives
- The kidnapping, the execution, and Hettinger's desperate escape
- The trials, appeals, and impact on police policy
- The psychological descent and the weight of living on
This is a meditation on fear, moral fracture, and what it means to survive when your partner does not—a quiet field that still echoes with irreversible loss.
Listener discretion is strongly advised: detailed accounts of kidnapping, execution-style murder, police trauma, and psychological distress.
