The 25-year-old man that authorities say is responsible for bombing a fertility clinic in Palm Springs, California, was reportedly a self-proclaimed “pro-mortalist” and believed that people should not be brought into the world without their own consent.

Guy Edward Bartkus — who was from Twentynine Palms — allegedly set off a car bomb on Saturday near the American Reproductive Center fertility clinic, killing himself and injuring four others.

Bartkus reportedly wrote in writings and recordings that he opposed the idea of bringing people into the world against their will, KCAL News reported, citing two law enforcement sources familiar with the investigation.

The writings he left behind were “anti-pro-life,” U.S. Attorney Bilal “Bill” Essayli said on X.

Bartkus was a resident of Twentynine Palms, a city in San Bernardino County that is located about 60 miles away from Palm Springs. The city serves as an entry point to the Mojave Desert and Joshua Tree National Park.

“This is probably the largest bombing scene that we’ve had in Southern California,” Davis said. 

American Reproductive Centers claims to be the first and only full-service fertility center and in vitro fertilization lab in Coachella Valley, according to its website. While the building was damaged, the IVF lab and its materials remained unharmed.

The FBI, the Palm Springs Police Department and the Palm Springs Fire Department did not immediately respond to Fox News Digital’s request for comment.
