The man authorities allege set off a deadly car explosion outside a California fertility clinic left behind chilling online writings

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.

One person was killed and at least four other people were injured after a vehicle exploded outside of a fertility clinic in Palm Springs, California.

The suspect behind the explosion at a Palm Springs, California, fertility clinic, Guy Edward Bartkus, died as a result of the attack. Law enforcement officials said Bartkus made a series of posts on social media, including a 30-minute audio recording, that supported anti-natalist views, the belief that nobody should have children.

An explosion outside a Palm Springs, Calif., fertility clinic late Saturday morning killed one person, injured four others and sent debris flying for blocks in all directions in the city about 100 miles east of Los Angeles.
