Authorities also say they disovered dye packs and wigs on the property. According to Deputy D.A. Perez, Jakubec robbed banks in San Diego County on June 25 and July 17, and got away with a "substantial amount" of money.
San Diego police reported a robbery at a Bank of America in the Sorrento Valley on June 25 that was first believed to be the work of the so-called "Geezer Bandit."
The suspect, who wore a Halloween-style old man mask, handed a teller a demand note and escaped with cash, according to San Diego police. On July 17, another local Bank of America branchwas robbed by a gray-haired, clean shaven man about 5'8", wearing a floppy straw hat and sunglasses, police said.
Jakubec's wife Marina, from whom he had recently separated, told the San Diego Union-Tribune that her Serbian-born husband had lost his job three years ago and she believes he had become unbalanced. "I am afraid for my husband's mental state," she said. "He's not well."
She told the paper that Jakubec had allegedly purchased chemicals and electronics with money she had earned, but she did not know what it was for.
According to court records, Jakubec was on probation after pleading guilty to shoplifting at an electronics store last year.
The gardener who stepped on the explosive material, 49-year-old Mario Garcia, suffered injuries to his left eye, left arm and chest.
Jakubec's court-appointed public defender did not immediately respond to a request for comment.
