2025 Palm Springs fertility clinic bombing

On May 17, 2025, a car bombing occurred at a reproductive center in Palm Springs, California, United States, leaving one person near the vehicle, later confirmed to be the perpetrator, dead, and four others injured. The explosion was described as one of the largest bombing investigations that the Federal Bureau of Investigation (FBI) has investigated in Southern California since the Aliso Viejo package bombing that killed one person and seriously injured two others in 2018. The perpetrator was identified as Guy Edward Bartkus, a 25-year-old man from Twentynine Palms, California. He was the only person killed in the attack, and his motives stemmed from ideologies that included an "anti-pro-life ideology", as well as promortalist and antinatalist beliefs, together described by the DOJ as "the belief that individuals should not be born without their consent and that non-existence is best", and by journalists quoting the FBI as "nihilistic ideation". Other journalists associate the bombing with the fringe philosophy of efilism, the idea "that human life is an evolutionary mistake and that people should choose not to procreate".

Bartkus's alleged co-conspirator, Daniel Jongyon Park, who shared his ideologies, had been returned to the U.S. after fleeing to Poland, but died by apparent suicide while in custody. Prior to and following his death at the Metropolitan Detention Center in Los Angeles on June 24, 2025, investigators amassed evidence of Park's having purchased and shipped, to Bartkus, all of the 270 pounds of ammonium nitrate traced to Bartkus's home and bomb-making, and Park's having visited Bartkus in Twentynine Palms from January 25 to February 8, 2025, contributing to their belief that the two had, in that period, experimented in bomb-making in Bartkus' garage before his flight to avoid arrest.
