Building Explosion Arrest

ORANGE — 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.

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.

Krajnyak had told friends she was afraid of Beal after he made threats following their breakup. Beal told investigators he felt betrayed when she told him she was in a relationship with another man, Hanna said.

Authorities suspect Beal, a partner in the salon, delivered the bomb to the business while Krajnyak was visiting family in Hungary.

Krajnyak had returned from that trip and had just finished treating a mother and daughter, who were at the front desk when she opened a cardboard box that exploded.

The blast knocked the two customers off their feet and the older woman told police it lit “everything on fire.”

First responders thought they were dealing with a car bombing or gas main rupture, said Paul Delacourt, the FBI’s assistant director in charge of the Los Angeles office.

The explosion blew out a big hunk of the building and body parts were found in the parking lot.

Investigators found two improvised explosive devices, three firearms and more than 100 pounds of explosive material during a search Beal allowed of his Long Beach house following the blast.

Beal, a model rocket hobbyist, denied making bombs and said then he did not have material for an explosion as powerful as the one he saw on television, according to court records.

Over nine months, investigators were able to make the case by piecing together fragments from the bomb they could connect to Beal, including a battery, a wire and boxes similar to the one that contained the deadly bomb.

“While the victim had expressed fears about Mr. Beal and he possessed material that could be used to manufacture a bomb, it was forensic evidence collected at the scene, analyzed and pieced together into a coherent whole that allowed us to file this case,” Hanna said.
