A man accused of aiding in the violent attack on a fertility clinic in Palm Springs was captured this week after a transcontinental manhunt crossed multiple borders.

According to ABC News, the FBI has arrested 32-year-old Daniel Jongyon Park, who allegedly supplied nearly 300 pounds of ammonium nitrate and helped plan a deadly bombing that claimed at least one life outside a California IVF clinic on May 17, 2025.

Park was arrested Tuesday night at John F. Kennedy International Airport in New York following his extradition from Poland. According to federal prosecutors, Park had fled the United States four days after the bombing and was taken into custody overseas on May 30. Officials say Park was attempting to evade capture after his alleged co-conspirator died in the explosion.

FBI links suspect to planning and materials arrangement

Authorities say that Park played a crucial role in assembling the bomb used in the eco-terrorist attack targeting the American Reproductive Centers fertility clinic in Palm Springs. The main bombing suspect, identified as 25-year-old Guy Edward Bartkus, was found dead near the detonated vehicle following the explosion. The blast also injured at least four people and severely damaged a nearby building, triggering a fire and partial structural collapse.

Investigators believe Park was not in the vicinity at the time of the bombing but instead supported Bartkus remotely. According to the FBI, Park had visited Bartkus in California during the early months of 2025 to conduct explosive tests in a garage. The materials allegedly used in the attack—ammonium nitrate combined with fuel oil—are similar to those used in the 1995 Oklahoma City bombing, according to federal authorities.

Prosecutors allege that Park initially shipped 180 pounds of ammonium nitrate from Seattle to Bartkus and then purchased an additional 90 pounds shortly before the bombing. All 270 pounds of explosives were allegedly used in the car bomb, although forensic analysts are still working to confirm the total explosive yield.

Investigators say suspects bonded over dangerous ideology

The FBI has described the incident as a planned act of terrorism guided by extreme ideological beliefs. Park and Bartkus reportedly shared a fringe philosophy known as pro-mortalism and anti-natalism—a belief system that questions the value of life and opposes birth because individuals cannot consent to being born. Officials say the two communicated through online chat forums and social media.

“The subject had nihilistic ideations, and this was a targeted attack against the IVF facility,” said Akil Davis, assistant director in charge of the FBI's Los Angeles field office. “Make no mistake, we are treating this... as an intentional act of terrorism.”

Additional allegations reveal that Park actively looked for others who held similar views, using online platforms as a recruiting tool. His posts reportedly promoted anti-life ideologies and urged action against organizations that supported reproductive technology.

Clinic operations continue despite damage and fear

Despite the devastating impact of the attack on its premises, the American Reproductive Centers fertility clinic has maintained operations. The clinic reported that no staff members were physically harmed during the incident, and all reproductive materials remained secure. Damage to the clinic forced them to relocate services temporarily across the street.

“We’re grateful to share that consultations, follow-ups, and ultrasounds are continuing with minimal disruption,” the clinic said in a social media statement. “Our team has made a nearly seamless transition... and we’re finalizing our new IVF lab and surgery center.”

Federal prosecutors are requesting that Park be denied release due to the severity of the charges. He faces counts of conspiracy to manufacture an unregistered destructive device and terrorism charges related to the attack in California. Park is expected to appear for a preliminary hearing in a federal court in Brooklyn before being transferred to California to face trial.

Why This Story Matters

This case highlights the rising threat posed by ideology-driven domestic terrorism. Fertility clinics, along with other health care providers, are increasingly seen as targets by radicalized individuals. Public awareness and timely intervention are crucial steps in preventing violence fueled by extremist beliefs.

Conclusion

Daniel Jongyon Park, 32, was arrested after federal authorities linked him to the deadly bombing outside a Palm Springs fertility clinic on May 17, 2025. Officials allege Park supplied nearly 300 pounds of ammonium nitrate and played a key role in planning the attack alongside Guy Edward Bartkus, who died in the explosion.

Park had fled to Europe days after the bombing but was apprehended in Poland and extradited to the U.S., where he now faces terrorism charges. Investigators say the pair were driven by anti-life beliefs and used online platforms to promote their ideology. The American Reproductive Centers clinic sustained damage but resumed operations quickly, confirming no loss of reproductive materials.
