Investigators are combing through the writings of a 25-year-old man believed responsible for bombing a Palm Springs fertility clinic.

The person killed in the Saturday explosion outside a fertility clinic in Palm Springs, California, is a 25-year-old from Twentynine Palms, the FBI said Sunday.

Residents described the intensity of a deadly explosion in Palm Springs, likening the frightening jolt in the resort community east of Los Angeles to a thunderclap or car crash.

Bartkus is believed to be the person who detonated a bomb at the Palm Springs American Reproductive Center, which offers services like IVF, because he was aligned with the pro-mortalist and anti-natalist movements—the idea that humans should not continue to procreate.

The attack, though unsuccessful, delivered a seismic shock to patients who feared for the safety of their embryos. But a firefighter’s risky plan averted disaster.

A White House official says the Trump administration is reviewing a list of recommendations to expand access to in vitro fertilization.

Bartkus has been named as a suspect in the bombing outside a Palm Springs fertility clinic, two law enforcement sources familiar with the investigation told KCAL News. He also allegedly stated in writings and recordings that he was a “pro-mortalist” — or against bringing people into the world against their will, the sources added.
