A suspect believed to be the perpetrator of the fertility clinic bombing in Palm Springs, Calif. Saturday, has been identified as 25-year-old Guy Edward Bartkus, a resident of Twentynine Palms, home to a large U.S. Marine Corps base about an hour's drive from Palm Springs, the FBI confirmed at a Sunday news conference. 

The suspect stated in writings or recordings that he was against bringing people into the world against their will, according to law enforcement sources familiar with the investigation.

The bomb used has been identified as a large vehicle-borne improvised explosive device and its blast could be felt more than a mile away from the blast zone.
