MILWAUKEE (AP) — A Wisconsin teenager charged in the deaths of his parents faces wider allegations that he killed them to “obtain the financial means” to assassinate President Donald Trump and overthrow the government, according to a recently unsealed federal warrant.
Nikita Casap, 17, was charged last month by Waukesha County authorities with first-degree murder, theft and other crimes in the deaths of his mother, Tatiana Casap, and his stepfather, Donald Mayer. Authorities allege the teenager fatally shot them at their home outside Milwaukee in February and lived with the decomposing bodies for weeks before fleeing with $14,000 cash, passports and the family dog. He was arrested last month in Kansas.
Casap, in custody at the Waukesha County jail on a $1 million bond, is due in court next month to enter a plea. County prosecutors have offered a glimpse of the federal allegations, which were outlined in an FBI warrant unsealed Friday.
Federal authorities accuse Casap of planning his parents’ murders, buying a drone and explosives, and sharing his plans with others, including a Russian speaker. His intentions are detailed in a three-page antisemitic manifesto praising Adolf Hitler. The warrant filed at the federal court in Milwaukee also contains excerpts of communications on TikTok and the Telegram messenger app.
“Casap appears to have written a manifest calling for the assassination of the President of the United States. He was in touch with other parties about his plan to kill the President and overthrow the government of the United States,” the search warrant says. “The killing of his parents appeared to be an effort to obtain the financial means and autonomy necessary to carrying out his plan.”
In court, prosecutors alleged Casap was in touch with a person who speaks Russian and shared a plan to flee to Ukraine. Authorities found him in Kansas with money, passports, a car and the family’s dog.
Federal prosecutors alleged Casap’s manifesto outlined his reasons for wanting to kill Trump and included ideas about how he would live in Ukraine.
Citing Casap’s writings, the federal warrant said the teenager wanted to spur governmental collapse by “by getting rid of the president and perhaps the vice president.”
Phone and online messages seeking comment were left Sunday for Casap’s public defender, Nicole Ostrowski. In court last month, she moved to dismiss some of the charges against her client, including theft, arguing that prosecutors had not laid out their case. She’s also noted her client’s age during court proceedings.
“He is young, he is still in high school,” she said on March 12.
County authorities also charged Casap with hiding a corpse, theft and misappropriating identification to obtain money.
Officers found the bodies of Tatiana Casap, 35; and Mayer, 51, on Feb. 28. Family members requested a well-being check after Mayer didn’t report for work and Nikita Casap skipped school for about two weeks.
Authorities believe the parents were killed weeks earlier. Prosecutors said in court that the couple’s bodies were so badly decomposed that they had to be identified through dental records.

We found no evidence that liberal Wisconsin Appeals Court Judge Chris Taylor has supported allowing noncitizens to vote.
Taylor and conservative state Appeals Court Judge Maria Lazar are running in the April 7 Wisconsin Supreme Court election.
A Lazar ad claimed Taylor is “pushing for noncitizen voting.”
Lazar’s campaign cited:
Taylor’s opposition, while a Democratic state lawmaker, to the Republican-backed 2011 state law requiring identification to vote.
Her introduction of a 2017 bill, which did not become law. It would have provided driver’s licenses to unauthorized residents, but the licenses would have been labeled: “Not valid for voting purposes.”
Taylor’s opinion, in a 2024 appeals court ruling, which said absentee ballots count even if voters’ witnesses fail to give election clerks their full address. Citizenship is required to vote in Wisconsin, but Wisconsin election officials generally do not verify citizenship when a person registers.

The president of Wisconsin’s largest mosque was detained by federal immigration agents, drawing accusations from local officials and religious leaders that the arrest was motivated by his statements against Israel.
Salah Sarsour, a Palestinian-born legal permanent resident of the United States, was taken into custody by nearly a dozen US Immigration and Customs Enforcement (ICE) agents on Monday in Milwaukee after he left his home, according to the Islamic Society of Milwaukee.
Supporters called for his immediate release on Thursday and his attorneys said he was detained on the grounds that he is a foreign policy threat. His attorneys say the claims have no merit.
Instead, they believe Sarsour, 53, was targeted for speaking out against Israel and for a conviction as a minor by Israeli military courts, which have faced scrutiny over allegations of limited due process and high conviction rates of Palestinians. Israel rejects those claims. The offenses included allegedly throwing rocks at Israeli officers, according to attorney Munjed Ahmad.
“Our government should not be doing the bidding of a foreign government,” Ahmad said of Israel. “There’s no question in my mind is that this is to stifle the discourse on the Palestinian narrative.”
Attorneys said Sarsour, born in the Israeli-occupied West Bank, has no criminal record in the US.
Sarsour’s attorneys have likened the case to that of Mahmoud Khalil, a former Columbia University activist who faces deportation because the federal government said he was a foreign policy threat.
An email message left on Thursday for ICE and the Department of Homeland Security was not immediately returned.
Sarsour has been the president of the Islamic Society of Milwaukee, the largest Islamic organization in the state, for five years. His attorneys say he’s held a green card for years and lived in the Milwaukee area. His wife and four adult children are US citizens.
His arrest prompted outcry from top elected officials, including Milwaukee’s mayor, Cavalier Johnson, who called it “an outrage”.
“He is a legal permanent resident. There is no substantive evidence he has done anything wrong,” Johnson said in a post on X. “This is another example of overreach and harm from the U.S. Immigration authorities.”
Sarsour is being held at county jail outside Indianapolis. His attorneys have filed a petition seeking his release.
“He is ready to fight tooth and nail to make sure that he’s not drug through the mud,” Ahmad said. “He wants to stay in this country.”
