Escondido house where explosive ingredients were discovered is considered too dangerous to reenter
Authorities are slowly trying to piece together how -- and why -- a 54-year-old Serbian emigre acquired large quantities of explosive ingredients that could be used to make the kind of bombs favored by terrorists, including insurgents trying to kill U.S. troops in Iraq and Afghanistan.
The work of a squad of local, state and federal explosives experts is being made more difficult because the one-story, stucco house in a leafy neighborhood in Escondido where the materials were found is considered too dangerous to reenter.
Investigators carted off several computers and numerous written documents in hopes of finding a motive for the alleged actions of George Djura Jakubec, a naturalized U.S. citizen, who now faces 26 bomb-making charges and two charges of bank robbery, all felonies.
Jakubec, who was on probation for a 2009 burglary conviction when he was arrested Nov. 18, remains in jail in lieu of $5-million bail.
The list of items seized from Jakubec’s rental home and backyard represents a virtual shopping list for bomb-makers, investigators said. Among the items are several kinds of acid, as well as hexamethylene triperoxide diamine (HMTD) and pentaerythritol tetranitrate (PETN).
Also seized at the home just outside the Escondido city limits were blasting caps, firearms, homemade grenades, and 50 pounds of hexamine, a bomb-making material, according to court documents.
Jakubec lived alone in the home, which he apparently had ringed with security cameras. His estranged wife, reportedly a Russian emigre, attended his arraignment Monday at San Diego County Superior Court in Vista, where he pleaded not guilty.
Rushing past reporters, Marina Ivanova said her husband is a "good man" and that she still loves him but that he had become "an obsessive collector" in recent years.
"He is crazy," she said tearfully as a sheriff's deputy escorted her to her car. "I think he lost his mind, he lost his mind or something."
Investigators who have been inside the house describe it in terms consistent with the habitat of someone classified as a compulsive hoarder.
The floor, tables, desks, chairs and virtually every horizontal surface were covered with papers, boxes, documents, cans, jars and other things. Even as they picked their way around the house for evidence on two occasions, investigators were careful not to jostle or step on things that could prove volatile or explosive.
Enough evidence was gathered inside the house for the weapons and bank robbery charges. There is no suggestion that Jakubec was a suspect in the bank robberies before authorities searched the house.
The bomb investigation began when a gardener was injured Nov. 18 in an explosion when he stepped on something in the backyard. As the gardener was taken to the hospital, San Diego County Sheriff’s Department deputies rushed to the scene of the explosion, which had frightened neighbors.
"Jakubec denied having anything explosive in the backyard, and appeared evasive and nervous during his conversation with the fire captain," according to an affidavit by sheriff’s Det. Benny Cruz. "… During their conversation, Jakubec tried to change the topic several times and was not forthcoming with some of the responses."
Later in the conversation, Cruz wrote, Jakubec admitted having explosive materials.
Cruz said experts on the scene determined that the materials are "extremely sensitive to shock, friction and heat, making it very dangerous to manufacture and handle."
The explosive materials, the affidavit states, are like those "currently being used in Iraq and Afghanistan by terrorist cells."
Jakubec was arrested on the spot.
Later, the Sheriff’s Department bomb squad sent a robotic device into the house to scan the interior. Bomb specialists also supervised several small controlled detonations. A stretch of nearby Interstate 15 was shut down.
Nearby houses were evacuated -- residents of the two closest houses have yet to be allowed to return to the blue-collar neighborhood.
Prosecutors said Jakubec is an unemployed software consultant. He has a contractor’s license and, in 1980, received a pilot’s license, according to public records. He also told investigators that he makes frequent trips to Mexico, although it is unknown whether he bought the explosive materials there.
Explosive experts next week plan to devise a strategy to safetly re-enter the house to gather additional evidence, officials said.
