Authorities called the attack terrorism and said Bartkus left behind nihilistic writings that indicated views against procreation, an idea known as anti-natalism.

the bureau believes it has identified the suspect connected to a bombing near a fertility clinic in Palm Springs, California, as 25-year-old Guy Edward Bartkus, and that he held "nihilistic" views.

Law enforcement sources told CBS that the Bartkus, the suspect, is a resident of Twentynine Palms, home to a large marine base about an hour away from Palm Springs.
