(TJV NEWS) Authorities have identified the man behind Saturday’s explosion at a fertility clinic in Palm Springs, California, as a 25-year-old with extremist “anti-natalist” beliefs, according to multiple reports from BBC News, NBC News, Breitbart, and the New York Post.

The blast occurred just before 11:00 a.m. at the American Reproductive Centers (ARC), a facility specializing in in vitro fertilization (IVF) and other fertility services. The explosion shattered windows and scattered debris across a wide radius, with its force reportedly felt more than a mile away (BBC News).

The FBI has named the suspect as Guy Edward Bartkus of Twentynine Palms. He died in the explosion, which also injured four other individuals, according to the New York Post. FBI officials have classified the attack as intentional, with Akil Davis, head of the FBI’s Los Angeles field office, stating: “This was an intentional act of terrorism… we will determine if it’s international or domestic terrorism.”

Authorities say Bartkus had posted online content — including a 30-minute audio recording — espousing anti-natalist views, which reject the notion of procreation and specifically oppose fertility treatments like IVF (NBC News). Investigators are examining these posts and writings as a potential motive.

BBC News reported that the explosion was caused by a large vehicle-borne improvised explosive device (VBIED). In addition to damage at the clinic, surrounding buildings were affected and some structures caught fire, Breitbart reports.

California Governor Gavin Newsom issued a statement following the attack, saying the state is working closely with local and federal agencies and advising the public to avoid the area, NY Post reported.

Law enforcement recovered two rifles — an AK-47 and an AR-style weapon — along with ammunition near the blast site, according to internal briefings cited by the Los Angeles Times and referenced by the New York Post.

Fortunately, the clinic’s lab, which contained eggs and embryos, remained intact, BBC News confirmed.

NBC News explained that “anti-natalism” is a belief system that argues against human reproduction, and investigators believe this ideology likely played a central role in Bartkus’s motivation for the attack.
