Authorities arrest boyfriend and business partner of woman killed in California day spa blast
Stephen Beal was arrested on suspicion of possessing an unregistered destructive device; investigators found the device at a Long Beach residence

An explosion that ripped through a California day spa on Tuesday, killing the business owner and injuring two customers, does not appear to have been the result of an accident, authorities said.
Authorities have arrested the business associate and boyfriend of a woman who was killed in an explosion that ripped through her Aliso Viejo day spa earlier this week.
Stephen Beal, 59, of Long Beach was arrested on suspicion of possessing an unregistered destructive device, FBI spokeswoman Laura Eimiller said Thursday.
Investigators found the device while serving a search warrant at a Long Beach residence, Eimiller said.

Beal is not being charged in connection with Tuesday’s explosion, which shook the two-story building so vigorously that people nearby thought there was an earthquake.
The spa owner, Ildiko Krajnyak, was killed in the blast, authorities said.
