vestigator targeted two city leaders, including the then-police chief, a former police chief, among others. This was quite a story in Fremont at the time because people didn't know when more bombs were going to go off, Tom Rogers, the former Alameda County prosecutor who tried Blach's case, told Bay Area News Group. The one bomb blew up a house completely, and the ATF said it was the biggest domestic bomb in the history of the country. Rogers, who went on to become a judge on the Alameda County Superior Court and retired in 2020 after a decade of service, said his investigations into the bombings were very worrisome, particularly after investigators determined the bomber had targeted law enforcement. He was very, very clever, and very, very shrewd, Rogers said. I was greatly relieved when we arrested him, because I knew he was locked up, and we didn't have to worry about him. Rogers said a jailhouse tipster recognized Blach and led authorities to find a storage locker filled with bomb parts, journals with his handwriting, and detailed plans to blow up an office building in Pleasant Hill and another Seattle home of an acquaintance he had a grievance, Rogers said. The evidence ultimately secured Blach's conviction, Rogers said. I had no doubt even before the storage locker, none whatsoever, Rogers said. I do think I prevented him from doing something in the future. Rogers said he also discovered Blach had numerous personal weapons at his home, including a collection of firearms. He had guns. I thought that he'd be able to shoot me, Rogers said Tuesday. I don't think about it too much. It does get me upset just thinking about it now. The two parole commissioners who heard his most recent petition, Michele Minor and Eleanore Adams, denied Blach's parole in 2023.

The parole commissioners also noted that Blach did not attend any therapy or programs to address his mental health. A prison clinician through his incarceration had diagnosed him with delusional disorder, and noted that he does continue to harbor delusional beliefs, and this factor remains highly relevant, Minor said. Blach decided not to discuss his crimes, but the board asked him whether he believed he planted the bombs - which he denied. The parole board recommended he enroll in therapy and other classes, such as anger management, and remain disciplinary free, after noting that he had three different violations from more than 22 years of his incarceration at the time. Blach said that he plans to enroll as a member of The People In Blue, a group of incarcerated San Quentin inmates and others who organize to reform parts of California's prison system. He also said he currently attends a class that teaches him living skills, and another course that teaches him self-awareness and emotional intelligence - he does not attend personal therapy or counseling. The convicted felon said Wednesday afternoon that he absolutely still believes he is not guilty and that police framed him for the bombings. One violation included a 2003 instance where prison officials confiscated a piece of paper from his cell that had a bomb recipe on it, Minor said. Blach told commissioners it was part of a Reader's Digest article that contained a picture of a bomb circuit and a story about Ahmed Ressam, the Millennial Bomber who was convicted of bombing the Los Angeles International Airport in 1999. Blach said he had the article because it contained information relevant to his case. Diane Letarte, who formerly represented Blach at his 2023 parole hearing, declined to comment on Blach's ongoing parole proceedings, noting she no longer represents him. But, she added, for elderly parole candidates, such as Blach, Letarte said the parole board is supposed to give certain special considerations, including an inmate's age, time already served and the programming and rehabilitation classes they've attended. They also consider whether the inmate has been disciplined or received any negative marks on his record during incarceration. The panel in general is saying if you can't follow rules in prison, you won't follow them in real life, Letarte said. Blach's minimum sentence runs until September 4, 2038, a few days shy of his 90th birthday. Bay Area News Group News Researcher and Librarian Veronica Martinez contributed to this report.
