Aliso Viejo blast: Mystery explosion kills woman in Orange County California

The deadly explosion that killed one woman and injured three others at an office building in the USA state of California was not an accident, said authorities on Wednesday.

Remnants of an explosive device were found inside the badly damaged spa where the powerful explosion Tuesday afternoon shook the city of Aliso Viejo, about 50 miles (80.5 kilometers) south of Los Angeles, and tore a corner off the building that houses medical offices.

As reported by the Fox News, local police have concluded that the explosion was not carried out as part of any larger plot and further no connection with any extremist group has been established.

The current theory is Krajnyak was killed by a parcel bomb, though it is not confirmed whether it was a targeted attack.

The blast had blown off the side walls of the medical office building, exposing insulation and framing as well as damaging the first-floor suite.

Friends said she was estranged from her husband but that the two still lived together got along.

The officials were briefed on the investigation but not authorized to discuss the matter publicly and spoke on condition of anonymity.

A USA official briefed on the investigation, speaking on condition of not being identified by name, told The Associated Press the explosion is being investigated as intentional and investigators believe the blast may have come from a package.

Formal identification of the body was continuing but authorities believe it was Ildiko Krajnyak (IL-di-koh KRY-nyak), a licensed cosmetologist, who owned the spa.

A USA official says a deadly explosion at a Southern California office building is being investigated as an intentional act and investigators believe the blast may have come from a package. When Krajnyak was home, she cared for her mother, who needed constant care, the neighbor said.

Krajnyak always put her family first, White said.

Krajnyak lived in the Orange County community of Coto de Caza.

However, he says no explosive device has been found in the building and investigators still aren't saying whether the explosion was accidental or intentional.

Two other people, believed to be patrons, suffered injuries which required surgery and are expected to survive. Area residents said the flurry of activity has come as a shock to them.

Agents from the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives were at the scene Tuesday night. "Investigation is in (the) early stages, as information is confirmed we will share it". Neighbors said Krajnyak's college-aged son was away at school at the University of Washington in Seattle when he learned of the blast that killed his mother.

Investigators are searching for clues about an explosion at a Southern California medical office that left a woman dead and three other people injured.

Orange County Fire Authority Chief Brian Fennessy says 10 engines and 70 firefighters were dispatched in response to a 1:09 p.m. Tuesday call from Aliso Viejo.

Witness Mary McWilliams tells the Orange County Register that she saw two burned women stagger from the building.

There's no word yet on a motive for the explosion.
