CUMBERLAND, Md. — A Maryland court on Tuesday ordered a blogger known as Ziz who leads a cultlike group connected to six killings held without bail.

The blogger, Jack LaSota, 34, of Berkeley, California, was arrested Sunday along with Michelle Zajko, 32, of Media, Pennsylvania, and Daniel Blank, 26, of Sacramento, California. They face charges including trespassing, obstructing and hindering and possession of a handgun in a vehicle.

The Zizians have been tied to the killing of U.S. Border Patrol Agent David Maland near the Canadian border in January and five other killings in three states.

LaSota, Zajko and Blank were arrested in Frostburg, Maryland, on Sunday afternoon.

The judge in the case ordered LaSota held without bail citing concerns about her being a flight risk and a danger to public safety. Prosecutors said LaSota “appears to be the leader of an extremist group known as Zizians” that has been linked to killings.

The three were expected to appear remotely for a bail hearing Tuesday at Allegany District Court in Cumberland, Maryland, court officials said.

The Zizians have been tied to the death of a woman during an attack on a California landlord in November 2022, the landlord’s subsequent slaying in January, the December 2022 deaths of Zajko’s parents in Pennsylvania and a highway shootout last month in Vermont that left U.S. Border Patrol Agent David Maland and a car passenger dead.

A Frostburg resident told police he wanted three “suspicious” people off his property after they’d parked two box trucks there and asked to camp for a month, according to police documents.

They were dressed in black and two wore gun belts holding ammunition, according to police. Officers found a rifle in the back of one truck and a handgun on the front floorboard. Zajko, who refused to put her hands behind her back and was taken to the ground, also was carrying a handgun, police said.

Maland, 44, was killed in a Jan. 20 shootout following a traffic stop in Coventry, Vermont, a small town about 20 miles (32 kilometers) from the Canadian border. Felix Bauckholt, a passenger in the car, also died, and the driver, Teresa Youngblut, has pleaded not guilty to federal firearms charges.

Officials have said the guns they were carrying were bought by a person of interest in the Dec. 31, 2022, deaths of Richard and Rita Zajko in Chester Heights, Pennsylvania, and that Youngblut had been in close contact with a person of interest in a homicide in Vallejo, California.

Maximilian Snyder, who applied for a marriage license with Youngblut in November, is charged with the Jan. 17 stabbing death of Curtis Lind, a Vallejo landlord who had survived an earlier attack by members of the Zizian group and was set to testify against them.

Officials have offered few details of the cross-country investigation, but Associated Press interviews and a review of court records and online postings tell the story of how a group of young, highly intelligent computer scientists, most of them in their 20s and 30s, met online, shared anarchist beliefs, and became increasingly violent.

Their goals aren’t clear, but online writings included topics such as radical veganism, gender identity and artificial intelligence.

At the middle of it all is “Ziz,” the leader of the strange group whose members are sometimes called “Zizians” in online forums.

LaSota published a dark and sometimes violent blog under the name Ziz and, in one section, described her theory that the two hemispheres of the brain could hold separate values and genders and “often desire to kill each other.”

LaSota, who used she/her pronouns, and in her writings says she is a transgender woman, railed against perceived enemies, including so-called rationalist groups, which operate mostly online and seek to understand human cognition through reason and knowledge. Some are concerned with the potential dangers of artificial intelligence.

LaSota has not responded to emails from the AP in recent weeks, and her attorney Daniel McGarrigle declined to comment on whether she is connected to any of the deaths. She’s wanted for arrest in two states for missing court appearances.

McGarrigle would only confirm Monday that he has represented LaSota and wouldn’t confirm her arrest or any details of the latest case. Attempts to reach attorneys for Zajko and Blank were not successful.

Pennsylvania state police records describe Daniel Blank as Michelle Zajko’s housemate in Vermont. In January 2023, police investigating the shooting deaths of Zajko’s parents detained both LaSota and Blank at a hotel where Zajko was staying. Blank was not charged. LaSota was charged with obstructing law enforcement and disorderly conduct.

The FBI said Friday that it arrested a Washington state woman in the fatal shooting of a U.S. Border Patrol agent in Vermont earlier this week.

Teresa Youngblut, 21, was charged in Monday’s killing of Border Patrol Agent David Maland, the FBI said, noting that Youngblut and a German man who died in the firefight that also killed Maland had been under surveillance for several days leading up to the confrontation.

Maland stopped Youngblut and Felix Baukholt on Interstate 91 in Coventry on Monday because Baukholt appeared to have an expired visa, according to an FBI affidavit. During the stop, Youngblut opened fired on Maland and other officers and Baukholt tried to draw a gun but was shot, the affidavit states. At least one border agent fired on Youngblut and Baukholt, but authorities haven’t specified whose bullets hit whom.

Investigators had been performing “periodic surveillance” of the pair since Jan. 14 after an employee at a hotel where they were staying reported concerns about seeing Youngblut carrying a gun and both of them wearing all-black tactical gear. Investigators attempted to question them but the pair declined to have an extended conversation and said they were in the area looking to buy property.

About two hours before the shooting, investigators watched Baukholt exit a Walmart in Newport with two packages of aluminum foil. According to the affidavit, he was seen wrapping unidentifiable objects while seated in the passenger seat.

Authorities later found a ballistic helmet, night-vision goggles, respirators and ammunition in the car, along with a package of shooting range targets, some of which were used. They also found two-way radios, about a dozen “electronic devices,” travel and lodging information for multiple states and an apparent journal.
