After more than three years, Pennsylvania authorities have announced a break in one of the state’s most notable cold cases – the murder of a married couple in a well-to-do suburb of Philadelphia.

The slain couple’s daughter, Michelle Zajko, has been charged in the 2022 killing that rattled the small community of Chester Heights, authorities said Wednesday.

Zajko, 33, has ties to the so-called Zizians, a cultlike group of highly educated, AI-obsessed vegans , linked to several violent deaths across the United States. She is accused of arranging the murder of her parents, Richard and Rita Zajko, on the morning of her 30th birthday, after receiving a text message from her mother seeking to mend their broken relationship.

“It was an exhaustive investigation, and it took years to pull together, but we are finally at the point where we can say beyond any doubt that Michelle Zajko was at least in part responsible for the death of her parents,” Delaware County District Attorney Tanner Rouse said at a news conference.

Rouse added that investigators are still working to identify a second person captured on surveillance footage entering the Zajkos’ home ahead of the murder on Dec. 31, 2022.

“She did not act alone,” Rouse said, referring to Zajko. “At this time, we don’t know who her co-conspirators were.”

Christopher Nieto, a lawyer for Zajko, did not immediately respond to a request for comment.

The Zajkos were found dead on Jan. 2, 2023.

Rita, 69, had a gunshot wound to the back of her head, her autopsy found. Richard, 71, had been shot right hand and right temple, according to his autopsy.

At the news conference, Rouse said investigators assembled a substantial body of evidence against Michelle Zajko, including incriminating text messages, ballistics analysis and enhanced audio from surveillance footage in which a voice could be heard yelling, “Mom!,” around the time of the murders.

“We don’t have a smoking gun,” Rouse said. “It is piece after piece after piece of evidence that’s been collected painstakingly over years.”

The case drew renewed attention last year after a Border Patrol agent was killed in a shootout in northern Vermont.

The confrontation began when agent David Maland pulled over a car that was occupied by two people – Ophelia Bauckholt and Teresa Youngblut. Federal prosecutors say Youngblut opened fire on the agents; Bauckholt was fatally shot as she attempted to draw her own weapon. Youngblut was also shot but survived and has pleaded not guilty to two federal weapons charges.

Vermont prosecutors later disclosed that the person who supplied the guns used by Youngblut and Bauckholt was a person of interest in a double murder in Pennsylvania — a reference to the Zajkos’ killing. The Bureau of Alcohol, Tobacco, Firearms and Explosives, or ATF, later identified that person as Michelle Zajko.

All three — Zajko, Youngblut and Bauckholt — have ties to the group known as the Zizians, according to people familiar with the group.

The Zizians splintered off from the so-called rationalist community in Berkeley, California, which draws high-IQ individuals focused on what they consider existential threats like the rise of AI. The group has bene linked to multiple violent attacks over the past four years.

In 2022 members were accused of assaulting an elderly California man — an attack that left one of them dead after the man opened fire, according to police and prosecutors in Vallejo.

The man, Curtis Lind, was set to testify against his alleged attackers when he was fatally stabbed outside his home in January 2025. Another member of the group has been charged in the murder.

The group’s leader is believed to be Jack “Ziz” LaSota, an Alaskan computer scientist and blogger. Like several other members, LaSota is transgender and identifies as a female.

Ten days after the Zajkos were found dead, Pennsylvania state troopers arrived at a hotel near the Philadelphia airport in search of the murder weapon. They had a search warrant targeting Michelle Zajko, according to police records.

She was located in a room with LaSota and a third person. The troopers brought her to their barracks for questioning. But she refused to cooperate and was allowed to leave, according to a law enforcement affidavit.

What happened next no one could have expected.

Troopers told Zajko to wait in the lobby so they could return her car. She bolted instead, leaving behind her vehicle and $40,000 in cash that was found inside of it, according to the affidavit.

LaSota was charged with obstructing the investigation. After she was released on bail, she failed to show up in court, prompting the judge to issue a bench warrant.

The whereabouts of both Zajko and LaSota were unknown for years. But in February 2025, they were both arrested on charges of trespassing and weapons offenses in the western Maryland town of Frostburg.

Both have pleaded not guilty and are awaiting trial.

Rosanne Zajko, who is Michelle’s aunt, praised the investigators who worked the case.

“We don’t know yet if the trial will begin to heal the void in our lives and the ache in our hearts, but we do know the detectives, the DA’s office and we the family have done everything possible to achieve justice for Rita and Rick,” she said at the news conference.
