Federal investigators say a 17-year-old Wisconsin boy charged with killing his mother and stepfather also planned to assassinate President Donald Trump and provoke wider violence.

According to an unsealed FBI affidavit cited in the evidence packet, Nikita Casap of Waukesha is accused of conspiracy to assassinate the president, attempting to assassinate the president and attempting to use a weapon of mass destruction. The same filing says investigators found a manifesto while searching for a device believed to belong to Casap. The document allegedly called for Trump’s killing in order to ignite a race war and sow chaos.

The FBI said Casap discussed his plans with others on TikTok and Telegram and identified himself as a follower of the Order of the Nine Angles. In the evidence packet, the bureau describes that network as a neo-Nazi cult that advocates violence and terrorism to overthrow governments and destroy modern civilization. The affidavit also says Casap partially paid for a drone fitted with a dropping mechanism that could be used to deliver an explosive, Molotov cocktail or strong topical poison.

The case began as a homicide investigation. Casap was first charged after being stopped in Kansas while driving his stepfather’s Volkswagen Atlas. Prosecutors later added two counts of first-degree homicide, two counts of hiding a corpse, theft of property over $10,000 and two counts of misappropriating identification to obtain money. The FBI affidavit says his mother, 35-year-old Tatiana Casap, and stepfather, 51-year-old Donald Mayer, were killed before he was found on the road far from home.

Authorities also said Casap lived with the bodies for two weeks. The evidence packet says investigators found the victims’ driver’s licenses, spent shell casings and a Smith & Wesson .357 Magnum in the vehicle. Court reporting cited in the packet says the mother was found in a hallway covered with blankets and a towel, while the stepfather was found in a first-floor office beneath a pile of clothing.

The affidavit presents the killings as part of a broader plan, not an isolated family crime. One FBI allegation says the murders were an effort to secure the money and autonomy needed to carry out the attack. The filing also says Casap shared details of the plan with a classmate.

The case is significant because it joins a domestic homicide probe with allegations of extremist violence targeting a sitting president. The evidence packet does not include a response from Casap’s attorneys, who did not immediately respond to a request for comment. The accusations remain allegations, and the packet provides no court ruling on the assassination plot.

If prosecutors prove the allegations, the case could become one of the most unusual and serious federal prosecutions involving a juvenile suspect in recent years: a homicide case, an alleged extremist manifesto, social media discussion, and a claimed plan for an attack using a drone-style delivery mechanism.

For now, the core facts are those laid out in the affidavit: a teenager already charged in the killings of his parents is now accused by federal investigators of plotting a political assassination and of using the murders to enable that scheme.
