A member of the cultlike group known as Zizians has been charged with murder in the shooting of her parents at their Pennsylvania home on her 30th birthday, and a prosecutor said Wednesday that authorities don’t believe she was acting alone.
Michelle Zajko, who has been jailed in Maryland on other charges since February 2025, has been charged with murder, burglary and conspiracy charges in the deaths of Rita and Richard Zajko, Delaware County District Attorney Tanner Rouse said at a news conference. The prosecutor said she did not act alone.
Rouse said that Zajko is known to have been among those who killed her parents “to the extent that if she wasn’t the one who actually pulled the trigger, she was certainly aligned with those who did.”
Online court records didn’t immediately indicate whether Zajko had an attorney in the Pennsylvania case as of Wednesday. An attorney representing her in Maryland did not immediately respond to a message seeking comment, and the Delaware County Public Defender’s office declined to comment.
The couple was shot to death in their home on New Year’s Eve after police say a neighbor’s doorbell camera captured video of a car pulling up to their home in Chester Heights, a voice shouting “Mom!” and another voice exclaiming, “Oh my God! Oh, God, God!”
Michelle Zajko has denied any involvement, and in court filings suggested her father might have killed her mother and then himself.
“I didn’t murder my parents,” she wrote in an April 2025 “ Open Letter to the World.”
Authorities, however, had long described Zajko as a person of interest in the double homicide, two of the six deaths linked to a group of young, highly intelligent computer scientists who appear to share radical beliefs about veganism, animal rights, gender identity and artificial intelligence.
Since 2022, members have been tied to the death of one of their own during an attack on a California landlord, the landlord’s subsequent killing, the Zajkos’ deaths in Pennsylvania, and a highway shootout in Vermont that left a border agent and another Zizian dead.
Zajko, who is charged with providing the gun used to kill U.S. Border Patrol Agent David Maland in January 2025, was arrested in Maryland a few weeks later along with Daniel Blank and Jack “Ziz” LaSota, whom authorities describe as the group’s leader. Police who responded to a landowner’s complaint about suspicious people parked in box trucks on his property described them as having “ties with the Zizians Cult” and said they would be questioned about crimes across the country.
All three face state charges of trespassing and illegal gun and drug possession, while LaSota faces a federal charge of illegal gun possession by a fugitive. A judge recently granted a defense request for a competency evaluation in the federal case.
In court filings, LaSota’s attorneys said their client eschews the term Zizian and denies that she and her friends have formed a cult. Zajko has claimed authorities arrested the group in Maryland to prevent them from exonerating Teresa Youngblut, who has pleaded not guilty in Vermont to murder and could face the death penalty if convicted.
Zajko was living in Vermont at the time of her parents’ deaths and was questioned there by police shortly after they died. A few weeks later, officers briefly took her into custody at a Pennsylvania hotel but released her without charges. LaSota, staying at the same hotel, was charged with obstructing the homicide investigation and disorderly conduct.
Zajko had been estranged from her parents in the year leading up to their deaths, the prosecutor said. They were killed hours after Rita Zajko texted her daughter in an attempt to reconcile. “Her mother reached out and explained that she was sorry for the rift that had grown between them,” the prosecutor said. “That text went unanswered.”
A few hours later, at least two people entered the home. “The lights go on in the home, and Richard and Rita Zajko are executed,” he said.
