FBI Identifies Suspect in Palm Springs Explosion, Calls It Largest in Southern California

As of Sunday at 5 p.m., the FBI is calling the car bombing in downtown Palm Springs the largest explosion in Southern California’s history. New details continue to emerge about the suspect, 25-year-old Guy Edward Bartkus from 29 Palms, who investigators believe died in the blast and is now the prime suspect in what federal officials are classifying as an act of domestic terrorism.

According to the FBI’s Los Angeles field office, Bartkus was found deceased near a 2010 silver Ford Fusion sedan with California license plate 8HWS848, which authorities believe was used to detonate the explosive device. FBI Assistant Director Akil Davis said in a press conference Sunday morning that Bartkus is believed to have had “nihilistic ideation” and targeted the IVF clinic deliberately. Officials say Bartkus left behind a manifesto and may have attempted to livestream the attack.

All staff at American Reproductive Centers, the target of the blast, were safe, as the clinic was closed Saturday. In a statement, the center confirmed that all embryos stored on-site were unharmed. Desert Regional Medical Center also confirmed that the four people injured in the explosion have since been treated and released.

Authorities are now working to trace Bartkus’ movements between 6 a.m. and 11 a.m. Saturday, the period leading up to the blast. “We know when he entered the city,” said Davis. “But we need the public’s help identifying where he traveled inside Palm Springs before the explosion.”

Officials are asking anyone who may have seen the silver Ford Fusion or captured it on security footage to contact the FBI by calling 1-800-CALL-FBI or submitting tips at FBI.gov/PalmSpringsVehicleExplosion.

In a related development, tactical officers were seen late Saturday night at a home in 29 Palms, where a search warrant was executed in connection to the investigation. Neighbors expressed shock and concern, especially given the proximity to families and children.

Authorities say Bartkus’ writings and online activity expressed deep self-hatred and extreme views, including identifying as a “pro-mortalist” who believed life should end to prevent future suffering. A reported website and YouTube channel tied to him are under review for further evidence.

Road closures remain in effect in the downtown Palm Springs area as the investigation continues. North Indian Canyon Drive is closed from Vista Chino to Chia Road, and North Palm Canyon Drive remains shut down between Vereda Norte and Chia Road. Commuters are advised to seek alternate routes.

As law enforcement continues to piece together the timeline and motivations behind the attack, they’re urging anyone with relevant information—no matter how small—to step forward.
