A 17-year-old from Waukesha, Wisconsin, allegedly killed his parents as part of a plot to overthrow the United States government, including calls to assassinate President Donald Trump, according to newly unsealed federal records. After no one answered the door, a sheriff’s deputy entered the home and found Tatiana deceased, “likely from gunshot wounds,” and covered in blankets. The sheriff’s office then requested cellphone pings for Mayer and Casap, finding that both phones were located in the area of Laramie, Wyoming.
Authorities searched the Waukesha residence again, finding Mayer, also deceased from gunshot wounds and covered in blankets, in the first-floor office. Deputies found a receipt for a .357 magnum revolver but did not find the gun in the house.
Following an extensive review of security footage, cell phone records, and witness statements, authorities believe Mayer and Tatiana were killed on Feb. 11. Subsequent cellphone pings showed Casap’s phone stationary at a truckstop in Walcott, Iowa, on Feb.
24. Walcott police provided security footage showing the teen operating Mayer’s black Volkswagen Atlas SUV, traveling alone with the family dog. Authorities listed Mayer’s vehicle as stolen on the evening of Feb.
28, and entered Casap as a missing juvenile. A little more than an hour later, the WaKeeney Kansas Police Department saw and stopped Mayer’s SUV with Casap inside. Also referred to as 09A, the group “advocates for the use of violence and terrorism to overthrow governments and destroy modern civilization,” the FBI noted in the affidavit.
The agency said Casap, according to a review of his phone, was allegedly using the usernames “@accelerationist” and “Awoken” and had images and communications referencing a self-described manifesto about assassinating Trump, making bombs, and conducting terrorist attacks. The FBI found messages on Casap’s phone under the “Awoken” username where he allegedly discussed consuming the terrorist group’s teachings and being visited by the FBI in 2023 for what the bureau described as “unrelated internet IP activity.” In other messages under the “@accelerationist” username, Casap allegedly references a manifesto document with an unknown user.
“When the time comes for me to send my manifesto to you (so that you can spread it online), should it be pdf?” Casap allegedly asked the user. Investigators also found screenshots of a three-page document called “Accelerate the Collapse,” which had been generated on Feb. 28.
“The document appears to be the manifesto referenced by @accelerationist, in the messages with the unknown user in the above paragraph, calling for the assassination of the President of the United States in order to foment political revolution in the United States and ’save the white race‘ from ’Jewish controlled' politicians,” according to the affidavit. The third page contained images of Adolf Hitler with the text “HAIL HITLER HAIL THE WHITE RACE HAIL VICTORY.” The FBI included several excerpts from the alleged manifesto: The teen seemingly paid, at least in part, for the drone and explosives for an attack, investigators said, according to conversations Casap allegedly had with a user informing him how to convert a drone into a weapon of mass destruction.
A search of the teen’s phone also found images of Mayer’s credit and debit cards, as well as the username and password of a bank account. In March, a classmate told police that Casap had mentioned plans of killing his parents but did not have access to a gun, the affidavit says, adding that he then told the classmate he would befriend someone who owned a gun so he could steal it. The FBI also said that Casap had told the classmate that he was speaking with someone in Russia who was planning on overthrowing the U.
S. government and assassinating Trump. An arraignment for Casap is scheduled for May 7, according to the Waukesha County court docket.
