The house with “(expletive) Jews” spray painted outside on the sidewalk, according to court records.

The 26-year-old man they were looking for was known to San Lorenzo residents, who have made numerous reports about him since 2022, ranging from the bizarre to concerning. He regularly patrols his neighborhood dressed in army fatigues, sometimes with a machete tied around his neck, other times with a BB gun or air rifle in hand and sometimes yelling “Heil Hitler” as he made his rounds, authorities said in court filings.

When the suspect — identified as Isaac Garcia — was arrested on suspicion of vandalism, he allegedly admitted to cutting the wire of a surveillance camera in San Lorenzo, authorities said. But he assured the police he never would have done it if he’d known it was a police system, adding that he wants to be a police officer “so bad.”

The cost of the surveillance system was around $2,000, authorities said.

Prosecutors have charged Garcia with felony vandalism and possessing body armor as a prohibited person, a misdemeanor. Inside his house, authorities allegedly found numerous air rifles, a crossbow, a practice grenade and several fixed-blade weapons, according to court records.

Authorities also found a video on one of Garcia’s electronic devices that prompted a sexual assault investigation, which remains active, according to court records. There was a plethora of “extremist propaganda,” often targeting Jewish and transgender people, including memes Garcia allegedly posted to social media and saved on his phone, court records show.

Authorities say Garcia’s mental health struggles might be at the root of his alleged crimes, and that he was living alone at the time of the alleged vandalism. They have also linked him to several antisemitic graffiti incidents, all involving red spray paint or a black magic marker, with “near identical” handwriting, authorities said.

At a Jan. 16 court appearance, Garcia was released without bail by Judge Thomas Reardon. He is scheduled to enter a plea on Thursday morning, records show.

Quentin Helgren was indicted in late May by a federal grand jury on charges of distributing more than 50 kilograms of marijuana. The charge carries a maximum of 20 years in prison and a $250,000 fine, records show.

A criminal complaint filed against Helgren says that his legal troubles started with an investigation into a person who is now cooperating with the federal government. The unnamed informant is described in court records as someone who was putting on weekly clandestine cannabis sales in Virginia — a state where marijuana possession is legal but the commercial market is not — and allegedly hired Helgren as a courier.

Federal authorities raided the cooperating witness’ warehouse last January and found hundreds of pounds of marijuana, according to a criminal complaint. That’s when he or she decided to turn in Helgren, describing in detail several times in 2023 when Helgren allegedly flew 85-120 pounds of marijuana to Virginia on his Cessna, and was paid $12,500 to $15,000 per trip.

The Drug Enforcement Administration found cellphone data and hotel records that further established Helgren was flying between Oakland and Virginia throughout 2023, according to the criminal complaint.

Helgren was arrested in May in California and released from jail while the case is pending. His arraignment has been set for June 12, court records show. Federal prosecutors have also filed a petition to seize his 1978 Cessna as part of the criminal prosecution under asset forfeiture laws.

But this sly government chameleon may now be trapped by his own apparent sweet tooth. The lawyer for one of three Aryan Brotherhood members facing racketeering charges believes he may have caught Nehring lying under oath to cover up the eating of two donuts in 2019.

Before a grand jury five years ago, Nehring, a DEA special agent, testified he ate donuts from an Irish Mafia-connected heroin dealer who’d concealed drugs in the donut box. Yet just the other day, before a jury in a RICO case, Nehring denied he ate them. Called back to the stand for a third time last Monday, Nehring hedged his denial.

“I don’t think I did. Although it wouldn’t surprise me,” he said. “I love donuts.”

Now, defense attorney Knut Johnson wants to bring Nehring back on the witness stand — again — and impeach him with the grand jury transcript where he confesses to the donut eating. And lest anyone think this issue is a “silly” legal point, Johnson’s motion offers assurances that it is in fact, deadly serious.

“(Nehring) is unreliable, the jurors should not trust him, the police investigation is sloppy, and the case agent in charge of the government’s case does not seem to care about details,” Johnson wrote, adding that it showed an “unserious, unprofessional approach,” besides being potentially dangerous.

On Wednesday afternoon, Chief U.S. District Judge Kimberly Mueller granted Johnson’s motion.

Johnson’s client, William Sylvester, is charged with butchering a fellow inmate named Ronald Richardson in an attack caught on camera, a fairly straightforward allegation with only one real legal question: prosecutors say Sylvester did it to obey a standing order by the Aryan Brotherhood to attack skinhead gang members, while the defense says Richardson was a “known child molester” and not welcome on that prison exercise yard.

In order to prove a racketeering murder, prosecutors must establish a gang-motive for the Richardson killing. Authorities have also implicated Sylvester in assisting co-defendant Ronald Dean Yandell in directing heroin sales inside and outside of prison.

Here’s how the donuts play into the biggest effort in decades by the federal government to splinter the Aryan Brotherhood prison gang: In the late 2010s, Nehring started investigating some alleged heroin dealers associated with the Contra Costa-based Family Affiliated Irish Mafia, which led to his discovery that one of his suspects was spending a lot of time on the phone with an Aryan Brotherhood commissioner.

Testifying before a 2019 grand jury, Nehring described his interactions with Quesenberry and how one time she gave him a box of donuts, with heroin hidden under a false bottom that she crafted.

“Sounds like a lot of work,” offered Assistant U.S. Attorney Jason Hitt, perhaps attempting to elicit more details of Quesenberry’s drug concealment. But Nehring just continued to talk about donuts.

Nehring said colleagues teased him about it and told him, “you ate heroin,” but that he didn’t think the drugs touched the chocolatey goodness. “They were good donuts,” Nehring said.
