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.

WASHINGTON (AP) — The Trump administration on Wednesday reached a multi-state settlement with chemical giant Chemours Co. over years-long, illegal discharges of synthetic “forever chemicals” used to make products resistant to water, grease and stains. The settlement is the first by the federal government to resolve enforcement claims against a manufacturer of harmful chemicals known as PFAS.
Under the agreement, filed in federal court in West Virginia, Chemours will pay a civil penalty of $22.5 million for alleged violations and spend $90 million over 15 years to mitigate PFAS discharges in three states: West Virginia, North Carolina and New Jersey.
Chemours, a spin-off of chemical maker DuPont, also agreed to install PFAS pollution controls for and surface water discharges and air emissions at a West Virginia facility at an estimated cost of $60 million, supply clean drinking water to communities near its West Virginia and New Jersey sites at an estimated cost of $280 million; and implement controls to reduce releases of PFAS and other toxic chemicals from its facility in North Carolina, based on a pending independent assessment.
Combined, the penalties and relief programs are estimated to cost at least $450 million, the Justice Department said.
The settlement allows Chemours to continue manufacturing PFAS for commercial and military applications while preventing future contamination and protecting communities from existing pollution, said Adam Gustafson, principal deputy assistant Attorney General for the Environment and Natural Resources Division.
“The Trump administration recognizes the important role of Chemours for it commercial and military obligations,'' Gustafson said in an interview. “The settlement protects public health while preserving that important balance.”
The settlement against a major PFAS manufacturer “delivers on the Trump administration’s promise to make polluters pay and stop PFAS contamination at the source,” said Jeffrey Hall, assistant EPA administrator for enforcement and compliance assurance.
The agreement will greatly reduce PFAS contamination of water, land and air and even begin to mitigate past harm, Hall said. “This settlement brings Chemours into compliance with the law and holds it fully accountable,” he said.
In a statement Wednesday, Chemours said it has already begun planning and implementing operational improvements at its facilities and will take steps to mitigate future emissions and enhance existing programs.
"This settlement provides Chemours with greater clarity on future compliance requirements and actions to support long-term responsible manufacturing,'' spokeswoman Jess Loizeaux said.
The settlement comes as the Trump administration is expected to propose softening Biden-era limits on “forever chemicals” in drinking water, while delaying but keeping tough standards for two common types of the substance.
The proposal will start the formal process of rolling back parts of the first-ever limits on PFAS in drinking water finalized during former President Joe Biden’s administration. Officials at the time found they increased the risk of cardiovascular disease, certain cancers and babies being born with low birth weight.
The agency is committed to addressing Per- and Polyfluoroalkyl substances (PFAS) in drinking water while following the law and ensuring that regulatory compliance is achievable for drinking water systems, EPA Administrator Lee Zeldin said.
The settlement determined that facilities Chemours operates in the three states have discharged PFAS into the Ohio River, Cape Fear River and Delaware River, respectively, in violation of permits required by the Clean Water Act and state laws. Chemours also violated legal requirements under the federal Toxic Substances Control Act at all three facilities.
As a result of the alleged violations, people living near the facilities were exposed to illegal PFAS, officials said. PFAS are widely used and found around the world, with scientific studies showing that exposure to some PFAS in the environment may be linked to harmful health effects in humans and animals.
The violations continued for over a decade, the Justice Department said. The facilities were previously owned for many decades by DuPont. The settlement announced Wednesday does not resolve DuPont’s liability for past PFAS violations, officials said.
A federal judge last year ordered Chemours to stop discharging unlawful levels of cancer-causing chemicals into the Ohio River from the company’s Washington Works plant in West Virginia. The pollutants endanger the environment, aquatic life and human health, U.S. District Judge Joseph Goodwin wrote in the August 2025 order.
The West Virginia Rivers Coalition had asked Goodwin to require the company to immediately comply with its permit limits after violating them for more than five years.
DuPont, Chemours and another company, Corteva, agreed to pay New Jersey up to $2 billion last year to settle environmental claims stemming from PFAS. The federal settlement does not affect the state case.
North Carolina Attorney General Jeff Jackson called the settlement “an insult to the people of eastern North Carolina.”
His state is “ground zero for GenX contamination, but this deal does practically nothing to clean up our water,” said Jackson, a Democrat. GenX is a trade name for a synthetic chemical developed by Chemours as an alternative to PFAS but which has raised significant health and environmental concerns in its own right.
“Chemours made this mess, and Chemours should clean it up," Jackson said in a statement.
The federal consent decree calls for 14 specific treatment systems to reduce PFAS in wastewater, stormwater and groundwater from the West Virginia plant. Chemours will test drinking water near the West Virginia and New Jersey sites and provide treated or alternative clean water.
