Washington State Man Arrested on Federal Charges Alleging He Provided Material Support to Palm Springs Fertility Clinic Bomber

A Washington state man was arrested on a federal criminal complaint alleging he provided material support to the Palm Springs fertility clinic bomber by shipping and paying for significant quantities of ammonium nitrate – an explosive precursor – prior to the suicidal terror attack last month.

Daniel Jongyon Park, 32, of Kent, was arrested last night shortly after his flight from Poland arrived at John F. Kennedy International Airport in New York. Park is charged with providing and attempting to provide material support to terrorists and made his initial court appearance today in the Eastern District of New York.

“This defendant is charged with facilitating the horrific attack on a fertility center in California. Bringing chaos and violence to a facility that exists to help women and mothers is a particularly cruel, disgusting crime that strikes at the very heart of our shared humanity,” said Attorney General Pamela Bondi. “We are grateful to our partners in Poland who helped get this man back to America and we will prosecute him to the fullest extent of the law.”

“Park allegedly sent large amounts of explosive precursors to the man who drove a car bomb to a fertility clinic in Palm Springs, an attack that potentially could have killed innocent people,”  said FBI Director Kash Patel. “The FBI and our partners work together to find and hold accountable those who engage in domestic terrorism and other illegal activity. I also want to express my thanks to authorities in Poland for their vital assistance in this case.”

“This defendant is charged with shipping large quantities of explosive precursors to the man whose suicide bombing last month destroyed a fertility clinic in Palm Springs,” said U.S. Attorney Bill Essayli for the Central District of California. “Domestic terrorism is evil and unacceptable. Those who aid terrorists can expect to feel the cold wrath of justice.”

According to an affidavit filed with the complaint, Guy Edward Bartkus, 25, of Twentynine Palms, California, drove a car containing a bomb to a fertility clinic in Palm Springs on May 17. Bartkus detonated the bomb, killing himself, injuring numerous victims, destroying the fertility clinic’s building, and damaging surrounding buildings and areas. Bartkus’s attack was motivated by his pro-mortalism, anti-natalism, and anti-pro-life ideology, which is the belief that individuals should not be born without their consent and that non-existence is best.

Park – who shares Bartkus’s extremist views – shipped large quantities of explosive precursor materials to Bartkus, including approximately 180 pounds of ammonium nitrate. Days before the Palm Springs bombing, Park paid for an additional 90 pounds (40.8 kilograms) of ammonium nitrate that was shipped to Bartkus.

Park sent the first shipments of approximately 180 pounds (81.7 kilograms) of ammonium nitrate to Bartkus shortly before traveling to Bartkus’s residence, where he stayed with Bartkus from Jan. 25 to Feb. 8. Three days before Park arrived at Bartkus’s house, records from an AI chat application show that Bartkus researched how to make powerful explosions using ammonium nitrate and fuel.

During his stay at Bartkus’s residence, Park and Bartkus spent time in Bartkus’s room as well as in a detached garage “running experiments,” according to the affidavit. This was the same garage where law enforcement, during a search after the May 17 bombing, located significant amounts of chemicals commonly used in the construction of homemade bombs.

Four days after Bartkus conducted the suicide bombing, Park flew to Europe. On May 30, Park was detained in Poland and later was ordered deported to the United States. 

If convicted, Park would face a statutory maximum penalty of 15 years in federal prison. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

The FBI’s Inland Empire Joint Terrorism Task Force is investigating this matter. Considerable assistance was provided by the Palm Springs Police Department, the San Bernardino County Sheriff’s Department; the FBI’s legal attaché in Warsaw, Polish authorities, and FBI field offices in Seattle, New York, San Diego, Las Vegas, and Portland.  

Assistant U.S. Attorneys Sarah E. Gerdes and Anna P. Boylan for the Central District of California, and Trial Attorney Patrick J. Cashman of the National Security Division’s Counterterrorism Section are prosecuting the case.

A criminal complaint is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
