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.

A 25-year-old man believed to be responsible for an explosion that ripped through a Palm Springs, California, fertility clinic left behind “anti-pro-life” writings before carrying out the attack.

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.
