A California man was arrested for a spa bombing that killed his ex-girlfriend last year after the FBI linked explosive remnants to the suspect, his home and car.

Stephen Beal, 59, had been arrested shortly after the bombing last year, but explosives charges were dropped and he was freed when prosecutors questioned whether material found at his home constituted a “destructive device.” Further testing and investigation led to Beal’s arrest Sunday on suspicion of malicious destruction of a building that included a death, a charge that can carry a life sentence.

The May 15 bombing killed Ildiko Krajnyak, 48, and seriously wounded two female clients when she opened a box that erupted in a fiery explosion at the spa in the city of Aliso Viejo, about 50 miles south of Los Angeles.
