The Rapid Rise of Jon-Erik Hexum in 1980s Hollywood
Prior to his untimely death, American actor Jon-Erik Hexum was touted as the ‘next big thing’ in Hollywood and considered somewhat of a ‘sex symbol’. Born in New Jersey in November 1957 and educated at Michigan State University, the model-turned-actor officially launched his screen career in 1982. He quickly gained widespread recognition after securing the lead role of Phineas Bogg, a former pirate turned time traveller, in the NBC science-fiction television series Voyagers!
Hexum’s career gathered significant momentum through high-profile television appearances. He starred opposite Dame Joan Collins in the 1983 television film Making of a Male Model and made a guest appearance in an episode of Hotel, which aired directly after the hit series Dynasty. In 1984, Hexum was cast as Mac Harper in the 20th Century Fox action-adventure series Cover Up, appearing alongside Jennifer O’Neill, Antony Hamilton, and the late Richard Anderson. The role was widely expected to solidify his standing as a major television leading man.
The Fatal Prop Gun Incident on the ‘Cover Up’ Set
Production took a tragic turn on 12 October 1984 during the filming of the seventh episode of Cover Up in Beverly Hills. Delays mounted during shooting, and the 26-year-old actor became ‘bored’ while waiting around the soundstage. According to reports by People Magazine, a specific scene required Hexum’s character to load blank ammunition into a functional .44 Magnum revolver. As schedule setbacks continued, Hexum reportedly grew anxious, ‘frustrated’ and ‘stressed out’, prompting him to start handling and fiddling with the firearm.
Witnesses reported that Hexum ‘jokingly’ raised the revolver to his temple, allegedly asking the assembled Beverly Hills cast and crew: “Can you believe this crap?” He then pulled the trigger. Although the revolver was loaded with blanks rather than live rounds, the proximity of the weapon caused catastrophic physical trauma. The intense muzzle blast from the discharge fractured his skull, driving a quarter-sized piece of bone fragment directly into his brain and causing ‘massive haemorrhaging’, as detailed in a 1994 retrospective by Entertainment Weekly.

Emergency Care, Brain Death, and a Lifesaving Legacy
Emergency medical personnel rushed Hexum to Beverly Hills Medical Centre, where specialized surgical teams performed five hours of emergency surgery in an attempt to repair the damage. Despite medical intervention, Hexum slipped into a profound coma and was later pronounced brain dead. He was subsequently transported to San Francisco, where he died six days later surrounded by his mother, Gretha Olivia Paulsen, and his older brother, Gunnar.
In the wake of the tragedy, Hexum’s family made the decision to donate his organs to help patients facing critical medical conditions. According to archived reports from 1984, the actor’s heart was transplanted into the chest of a 37-year-old former Navy SEAL, Michael Washington, who later declared: “Because of this man, I’m alive today.” Subsequent reporting by the New York Post in 2018 documented that Hexum’s corneas restored vision for a 66-year-old man and a young girl, while his kidneys were sent to the Southern California Transplant Bank in Los Angeles for prospective recipients, and his skin grafts provided vital aid to a severely burned three-year-old boy.
Why This Matters
The death of Jon-Erik Hexum stands as one of the most prominent early warnings regarding the extreme dangers of blank-firing firearms on television and film sets. While blank cartridges lack a standard lead projectile, the immense gas pressure, unburned gunpowder, and wadding expelled at close range can be lethal.
Decades after the incident, the hazards of prop weapons continue to reverberate across the entertainment industry. In 2021, Hexum’s former Cover Up co-star Jennifer O’Neill reflected on the loss, noting Hexum was in the ‘pinnacle of his life and career’ when he ‘accidentally shot himself with a half-loaded prop gun while fooling around’. Emphasizing the enduring necessity of strict protocol, O’Neill told Fox News: “What a tragedy! Gun safety is essential and needs to be professionally addressed to spare the tragic loss of innocent lives.” She also praised his family’s ‘selfless’ decision to donate his organs, which left Hexum “[able] to save the lives of so many others in need following his fatal accident.”
