ESCONDIDO, Calif. (CBS 8/CNS) – A 1994 San Diego probate court file is shedding new light on the family history of the man accused of operating a bomb factory in his Escondido home.
The case file contains the last will and testament signed in 1979 by the parents of George Djura Jakubec. The document identifies the 54-year-old, unemployed computer software consultant by a slightly different name: Djuro George Jakubec.
Jakubec's parents are identified in the case file as Djuro and Erza Jakubec. Both were born in the former Yugoslavia, according to death certificates on file with the San Diego County Recorder's Office.
The mother, Erza Jakubec, died of natural causes in 1992 at the age of 72. The father, Djuro Jakabec, passed away in 1994 at the age of 61, also of natural causes related to heart disease.
At the time of his death, the senior Jakubec lived in a home on Calle Maribel in San Marcos and his profession was listed as "farmer." Erza Jakubec was listed as a "homemaker" on her 1992 death certificate, with a residential address on Vista Vicente Drive in Ramona.
The 1979 document described George Jakubec as an only child, with a half-brother from his mother's previous marriage. The records state Jakubec received $33,000 in cash from his father's estate after the San Marcos home on Calle Maribel was sold and probate closed in 1996.
Prosecutors have said George Jakubec is a naturalized United States citizen from Serbia, which was once part of the former Yugoslavia. His mother, Erza, was also listed as a U.S. citizen on her death certificate. In addition, both parents possessed U.S. social security numbers, records show.
Family court files reveal George Jakubec got married in Las Vegas in 1979 at the age of 23 to Mildred Marshall, but ultimately obtained a summary dissolution in 1983. He had no children from that three-and-a-half-year marriage.
Again in Las Vegas, in 2000, records show Jakubec married his current wife, Marina Y. Ivanova, 37, who now works as a computer engineer at a firm in Sorrento Valley. The couple was reported to be estranged, but they both appeared together at a small claims appeal hearing in downtown San Diego just three days prior to Jakubec's arrest in Escondido.
Both George Jakubec and his wife remain on probation from a 2009 shoplifting conviction in the North County, according to court records.
Jakubec pleaded not guilty Monday to 12 counts of possession of a destructive device, 14 counts of possession of the ingredients to make a destructive device, and two counts of bank robbery. He was arrested November 18 when an explosion on the property injured his gardener.
A November 19 search warrant served on the home at 1954 Via Scott in Escondido said bomb-clearing crews found hazardous chemicals, grenades, and jars containing explosive powder.
More homemade explosives and bomb-making materials were found in the cluttered home on Wednesday. Most of the explosives were left in the house, because they are too dangerous to remove, according to sheriff's deputies, who are working on a plan to dispose of the chemicals.
Hexamethylene triperoxide diamine, or HMTD, and pentaerythritol tetranitrate, or PETN, that was found in the house has been stabilized, deputies said.
PETN is the explosive compound that the Transportation Security Administration is hoping to detect though the use of full body scans at airports. It has been used in recent years by terrorists and suicide bombers, and is said to be an al-Qaida favorite. The sand-like compound is hard to sniff out and does not set off metal detectors.
A San Diego County hazardous materials crew last week removed about 4 liters of hydrochloric acid, 1 liter of nitric acid, 25 gallons of sulfuric acid and 50 pounds of hexamine from the property.
Prosecutors have not revealed any motive for the bomb-making cache, nor have they charged Jakubec with any crimes related to terrorism.
Wednesday's follow-up search of the home turned up evidence related to a series of armed robberies, deputies told reporters, without being more specific.
Jakubec is jailed in lieu of $5 million bail. His next court hearing is set for December 3.
