Authorities have identified a 25-year-old man believed to be behind the bombing of a fertility clinic in Palm Springs, California. He reportedly described himself as a “pro-mortalist” and held the belief that people should not be born without their consent.

The individual, Guy Edward Bartkus from Twentynine Palms, allegedly detonated a car bomb on Saturday near the American Reproductive Center fertility clinic, resulting in his death and injuries to four others.

Bartkus is said to have expressed his opposition to the notion of bringing people into the world without their permission in his writings and recordings, according to a KCAL News report, which cited two law enforcement officials familiar with the case.

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.
