Michelle Zajko, a member of the cultlike group known as the Zizians, has been charged with murder in the shooting deaths of her parents at their Pennsylvania home on what would have been her 30th birthday, authorities announced Wednesday.
Background
Rita and Richard Zajko were found shot to death inside their Chester Heights home on New Year's Eve. Investigators say a neighbor's doorbell camera captured disturbing audio from that night: a car pulling up to the residence, a voice calling out "Mom!" followed by exclamations of "Oh my God! Oh, God, God!" The recordings proved pivotal in piecing together the events leading to their deaths.
Delaware County District Attorney Tanner Rouse revealed at a Wednesday news conference that Michelle Zajko had been estranged from her parents for approximately a year before the killings. Hours before the double homicide, Rita Zajko had texted her daughter attempting reconciliation. "Her mother reached out and explained that she was sorry for the rift that had grown between them," Rouse said. "That text went unanswered." Within hours, at least two individuals entered the home.
"The lights go on in the home, and Richard and Rita Zajko are executed," the prosecutor described. Following the murders, Michelle Zajko, then living in Vermont, was questioned by local police. Weeks later, she was briefly taken into custody at a Pennsylvania hotel before being released without charges at that time.
The Investigation
Michelle Zajko has been jailed in Maryland since February 2025 on unrelated charges. She has now been charged with murder, burglary and conspiracy in connection with her parents' deaths. DA Rouse emphasized that authorities do not believe she acted alone in the killings.
"She was 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," Rouse stated.
The charges are the latest development in an expanding criminal investigation into the Zizians, a group authorities describe as comprising young, highly intelligent computer scientists sharing radical beliefs about veganism, animal rights, gender identity and artificial intelligence. Since 2022, members have been linked to six deaths across multiple states: one of their own during an attack on a California landlord, that landlord's subsequent killing, the Zajkos' deaths in Pennsylvania, and a January 2025 highway shootout in Vermont that left U.S. Border Patrol Agent David Maland dead along with another Zizian.
In Maryland, Zajko was arrested alongside Daniel Blank and Jack "Ziz" LaSota, whom authorities identify as the group's leader. All three faced state charges including trespassing and illegal gun and drug possession. LaSota also faces a federal charge of illegal gun possession by a fugitive. A judge recently granted a defense request for a competency evaluation in that federal case.

What's Next
Online court records did not immediately indicate whether Zajko had an attorney representing her in the Pennsylvania case as of Wednesday. An attorney representing her in Maryland did not respond to requests for comment. The Delaware County Public Defender's office declined to comment.
Zajko has denied involvement in her parents' deaths, and in an April 2025 "Open Letter to the World," she wrote: "I didn't murder my parents." In court filings, she suggested her father might have killed her mother and then himself — a claim contradicted by physical evidence and witness accounts. Her next Pennsylvania court appearance has not yet been scheduled as authorities continue investigating other potential participants in the killings.
