Summary

Nikita Casup, a 17-year-old high school student with good grades and plans for college, murdered his mother and stepdad, Tatiana Casup and Donald Mayor, in their Wacaaw, Wisconsin home around February 11, 2025. He lived with their bodies for approximately two weeks, using candles to mask the smell, before fleeing on a multi-state road trip. The crime was discovered when Don's mother, concerned by bizarre text messages, requested a welfare check, and Nikita's school reported his two-week absence. Authorities tracked Nikita through phone pings and found him in Kansas with the family dog, $14,000 in cash, stolen jewelry, and the murder weapon (a .357 Magnum owned by his stepdad). Crucial evidence included camera footage from the home showing Nikita lighting candles and a FaceTime call where he displayed his stepdad's body. An analysis of his iPhone revealed messages in Russian discussing his escape to Ukraine and asking about headphones to protect against gunshots. Further investigation by the FBI uncovered disturbing conversations on TikTok and Telegram, where Nikita, using usernames like 'awoken' and 'accelerationist,' discussed neo-Nazi ideology (Order of the Nine Angles), terror attacks, and a three-page manifesto detailing his plan to kill the US President (specifically Trump) to incite political revolution and 'save the white race.' He intended to use the stolen money to buy a drone for a terror attack. Nikita Casup pleaded guilty to two counts of first-degree intentional homicide on January 8, 2025, facing life imprisonment.
This case highlights the hidden dangers of online extremist radicalization, demonstrating how a seemingly normal teenager can harbor violent, politically motivated ideologies leading to horrific acts. It underscores the critical role of digital forensics in uncovering motives and evidence in modern criminal investigations, and the challenges law enforcement faces in identifying and intervening in such cases, especially when online activity is flagged but not fully acted upon until after a tragedy.

Insights

1Two-Week Coexistence with Deceased Parents

Nikita Casup lived in his home with his parents' bodies for approximately two weeks after their murders. He used candles to mask the smell, as evidenced by camera footage found in his car.

Police found Don and Tatiana's bodies covered in blankets. Video footage from a camera in the office showed Casup lighting candles in the days before he fled, using them to 'mask the smell as he lived with his parents' bodies for roughly 2 weeks.'

2Extremist Motive and Presidential Assassination Plot

Casup's motive for killing his parents was to obtain financial means to fund a plot to assassinate the US President, overthrow the government, and commit terrorist attacks, driven by neo-Nazi ideology.

Investigators found disturbing conversations in Russian on TikTok and Telegram, and a three-page manifesto on Casup's phone. The manifesto detailed killing the President 'to create a political revolution to save the white race from Jewish controlled politicians,' praising Adolf Hitler, and specifically targeting Trump.

3Digital Footprint and External Influence

Casup's online communications revealed he was actively engaged with extremist ideologies and potentially receiving instructions or encouragement from others regarding his plans.

Messages on Telegram included asking 'How long will I need to hide before I will be moved to Ukraine?' and 'So, while in Ukraine, I'll be able to live a normal life even if when it's found out I did it?'. Another message asked about headphones to protect hearing from a .357 Magnum. He also discussed a terror attack, asking 'What country do you think will get the blame for this?' with a user replying, 'Russia will be blamed for it. This is the goal.'

4Calm Demeanor vs. Plea Hearing Nerves

Nikita maintained a remarkably calm and composed demeanor during his initial interrogation, even discussing future college plans, but showed noticeable physical signs of distress during his guilty plea hearing.

The host notes, 'It is truly stunning to think of what this teenager did to his parents and then to see him just so calm in this setting.' (). However, during the plea hearing, the host points out, 'Look at his chair shake as he is speaking.' ()
