The FBI declared a “blast zone” and cleared residents in the Twentynine Palms neighborhood over concerns that bomb-making materials could be inside a home.

Guy Edward Bartkus was identified as the suspect accused in the bombing targeting a Palm Springs, CA, fertility clinic, and authorities are investigating a possible manifesto, according to the FBI. The bombing occurred on May 17,

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.

Bartkus was identified as the key suspect by the FBI on Sunday, after his body was discovered near a burned-out vehicle outside the clinic. He had reportedly attempted to livestream the explosion, with a camera found set up on a tripod nearby, although no footage was uploaded online.
