The suspect killed in what authorities say was a targeted attack on a Palm Springs fertility clinic explosion has been identified as 25-year-old Guy Bartkus. Bartkus was the sole person killed in the blast.

Bartkus has been named as a suspect in the bombing outside a Palm Springs fertility clinic, two law enforcement sources familiar with the investigation told KCAL News. He also allegedly stated in writings and recordings that he was a “pro-mortalist” — or against bringing people into the world against their will, the sources added.
