The car bombing outside a California fertility clinic that killed one person and injured four others appears to have been driven by anti-natalist ideology, according to two senior law enforcement officials briefed on the incident.

An FBI official said on Sunday 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.

Guy Edward Bartkus, 25, is allegedly responsible for bombing a fertility clinic in Palm Springs, California. He was reportedly a self-proclaimed "pro-mortalist" and left behind "anti-pro-life" writings.
