A Wisconsin teenager allegedly involved in his parents’ deaths is facing more serious accusations as federal documents suggest he aimed to kill them to finance an assassination plot against President Donald Trump and to topple the government.
Seventeen-year-old Nikita Casap, was charged in Waukesha County last month with first-degree murder and several other offenses related to the deaths of his mother, Tatiana Casap, and stepfather, Donald Mayer. Authorities claim that the teenager shot them in February at their Milwaukee home and lived with the bodies in a state of decay for weeks before fleeing with $14,000 in cash, passports, and the family pet. He was later apprehended in Kansas.
Currently held in Waukesha County jail on a $1 million bond, Casap is expected in court soon to submit a plea. Recent unsealed federal documents provide more insight into the wider allegations, as outlined by the FBI warrant. Federal agents allege that Casap planned the murders of his parents as part of a broader scheme involving the purchase of a drone and explosives, and shared these details with others, including a Russian speaker. A three-page antisemitic manifesto that praises Adolf Hitler reportedly outlines his intentions. Evidence was gathered from communications on TikTok and the Telegram messenger app.
According to the search warrant, “Casap appears to have written a manifesto calling for the assassination of the President of the United States. He communicated with others regarding his plan to kill the President and overthrow the government.” The warrant suggests that killing his parents was a way to gain “financial means and autonomy” necessary for his scheme.
In court, it was presented that Casap was in contact with a Russian-speaking individual and had purported plans to escape to Ukraine. He was eventually found in Kansas possessing money, important travel documents, a vehicle, and the family dog.
The federal warrant suggests that Casap’s manifesto detailed motives for targeting Trump and imagined a life in Ukraine after his planned actions. It also noted that Casap envisioned disrupting the U.S. government by taking out key figures including the president and vice president.
Casap’s public defender, Nicole Ostrowski, has received phone and online messages for comment. In a previous court appearance last month, she contested some charges, like theft, arguing insufficient evidence from prosecutors, while emphasizing her client’s youth, noting, “He is young, he is still in high school.”
Alongside murder charges, Casap faces charges of hiding a corpse, theft, and illegally using identification for financial gain. Authorities discovered the bodies of Tatiana Casap, 35, and Mayer, 51, on February 28, following concern from family members after Mayer failed to show up for work and Casap was absent from school for two weeks. Investigators believe the murders occurred several weeks prior, with the couple’s advanced decomposition necessitating dental record confirmation for identification.
