SANTA ANA, Calif. - UPDATE: 5/21/2018 10:41 a.m. A Southern California man who was arrested on an explosives charge after a blast killed his former girlfriend last week at her day spa is scheduled to appear in court.
Fifty-nine-year-old Stephen Beal is set to appear in federal court in Santa Ana Monday afternoon.
Beal is charged with possessing an unregistered destructive device that the FBI says was found at his home.
He has not been charged with the blast that killed 48-year-old Ildiko Krajnyak (IL-di-koh KRY-nyak) on May 15 when she opened up a cardboard box at the spa in the city of Aliso Viejo south of Los Angeles.
Beal and Krajnyak dated until recently and remained business partners.
Beal did not enter a plea during a court appearance last week and his public defender would not comment.
UPDATE: 5/16/2018 1:18 p.m. Authorities say they believe a woman killed in an explosion at a Southern California office building ran a day spa there.
Orange County Undersheriff Don Barnes says the formal identification of the body is continuing Wednesday but authorities believe it is that of Ildiko Krajnyak (IL-di-koh KRY-nyak), a licensed cosmetologist.
The explosion Tuesday badly damaged a two-story building in the city of Aliso Viejo and injured three other people, including two who remain hospitalized.
Krajnyak lived in the Orange County community of Coto de Caza.
A neighbor who would only identify herself as Tiffany told The Associated Press that Krajnyak lived with her husband and her mother and has a son at Washington State University.
The neighbor says Krajnyak and her husband were separated but still living in the same house. The neighbor says Krajnyak was her mother's caretaker and describes the husband as a massage therapist and nice man.
UPDATE: 5/16/2018 11:00 a.m. Two officials have told The Associated Press that an office in a Southern California medical building was targeted by an explosive package.

One woman was killed and three other people were injured in Tuesday afternoon's explosion in Aliso Viejo.
One of the officials said one of them was believed to be the target.
