The FBI believes the suspect in the Palm Springs explosion left behind "anti-pro-life" writings before carrying out the attack, officials said.

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.

Guy Edward Bartkus has been linked to the Palm Springs explosion. He allegedly mentioned Sophie Tinney, a woman who died from gunshot wounds, on his website.
