FBI: 'Exhaustive' work links California man to deadly bomb

ORANGE, Calif. (AP) — A California man was arrested for a spa bombing that killed his ex-girlfriend last year after a painstaking analysis linked explosive remnants to the suspect, his home and car, federal prosecutors said Monday.

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.
