Wisconsin Teen Accused of Killing Parents to Fund Plot Against Former President Trump and Overthrow Government, Federal Warrant Reveals

 April 13, 2025 Waukesha County, WI

In a chilling case that has shocked both law enforcement and the public, a 17-year-old Wisconsin boy already charged with the brutal murders of his mother and stepfather is now facing explosive new allegations. A recently unsealed federal search warrant accuses the teen of killing his parents to secure funds to assassinate former President Donald Trump and attempt a violent overthrow of the United States government.

The teenager, Nikita Casap, of Waukesha County, is currently in custody and facing two counts of first-degree intentional homicide in the February deaths of his mother, Tatiana Casap, and his stepfather, Donald Mayer. But according to federal documents unsealed this week, the slayings were allegedly just the beginning of a much larger and deeply disturbing plot.

Federal Authorities Uncover Darker Intent

According to the warrant filed by the FBI, Casap fatally shot his parents in the family’s home and remained in the residence for approximately two weeks, hiding the bodies while he gathered money, identification documents, and supplies.

Law enforcement officials allege that Casap’s actions were part of a premeditated plot to carry out a political assassination and wage a campaign of domestic terror. In journals, online chats, and a manifesto recovered from his electronic devices, Casap allegedly expressed a desire to “end the current regime,” naming Trump as his central target. He also referenced plans to launch coordinated attacks on key government sites.

The teen allegedly wrote that he needed money to purchase weapons, drones, and explosives — and that the only way to acquire those funds quickly was to kill his parents and take their savings.

“He believed that by removing his parents and taking their financial resources, he could finance a violent political uprising,” the affidavit stated.

Manifesto and Online Activity Paint Alarming Picture

The FBI says Casap maintained a disturbing online presence, frequently interacting with extremist groups through platforms such as Telegram, TikTok, and various encrypted messaging apps. Authorities say he communicated with at least one associate fluent in Russian, and referenced military-style tactics and bomb-making techniques.

Investigators also found that he had ordered drone parts and chemical components consistent with improvised explosive devices (IEDs), and that he discussed using drones to conduct reconnaissance and potentially launch attacks.

His writings revealed admiration for past political assassins and terrorists. In one entry, he reportedly said, “I will be the spark that lights the fire in America. A new order is coming.”

Apprehension and Charges

Casap fled the state after the killings, traveling with over $14,000 in cash, multiple passports, and the family dog. Authorities launched a multi-state manhunt, ultimately capturing him in Kansas, where he had reportedly begun assembling materials for the next phase of his plan.

He is currently being held in Waukesha County Jail on a $1 million bond. Prosecutors have filed charges of first-degree intentional homicide, and federal prosecutors are now weighing additional charges, which may include attempted use of weapons of mass destruction, interstate threats, and conspiracy to assassinate a former U.S. president.

Casap is expected to appear in court for a preliminary hearing on May 7, where more details may emerge.

Community and National Reaction

The case has rattled the quiet suburban community where the Casap family resided. Neighbors described the teen as intelligent but socially withdrawn, while school officials said he had no prior history of violence.

“This is something we never imagined could happen in our neighborhood,” one neighbor said. “We’re all in shock.”

Across the country, officials and experts are expressing renewed concern about youth radicalization, particularly the role of online platforms in spreading extremist ideologies to vulnerable individuals.

“This case is a tragic reminder that radicalization doesn’t have an age limit,” said Dr. Eliza Manes, a terrorism analyst. “What’s especially alarming is the combination of personal violence and political extremism — that’s a dangerous and growing pattern.”

Ongoing Investigation

Authorities are continuing to comb through the teen’s communications, devices, and financial records to determine whether he acted entirely alone or had assistance. Investigators are also probing the extent of his interaction with international individuals and whether any foreign influence may have been involved.

Officials urge anyone with information about the case or the teen’s online activity to contact the FBI or Waukesha County authorities.
