In court documents, federal authorities claimed that a Wisconsin teenager killed his parents to “obtain financial means and the autonomy necessary” for him to kill Donald Trump and to overthrow the U.S. Government.

Nikita Casap (17) was arrested and charged in March with two counts each of murder of the first degree and concealing a corpse. Other charges include theft over $10,000 and misappropriating identification to obtain money.

Documents in court show that federal investigators are investigating charges such as conspiracy, presidential murder, and the use of weapons.

According to a Waukesha Sheriff’s Department press release, the Waukesha County Sheriff’s Department found the teen’s mother, Tatiana Casap, and stepfather, Donald Mayer, dead in their home on March 1.

The sheriff’s department issued a warrant for a search of the phone of the teenager. They found materials related to “The Order of Nine Angles,” which, according to investigators, is a “network of individuals who hold new-Nazi views that are racially motivated.”

According to documents filed in federal court, the Federal Bureau of Investigation examined documents written allegedly by the teen. The documents called for the assassination of Trump along with the launch of a revolution “to save the white race.”

According to court documents, the alleged writings show images of Adolf Hitler along with the text “HAIL HITLER HAIL WHITE RACE HAIL VICTORY.”

He was in contact with other parties regarding his plan to overthrow and kill the United States President. He paid, at least partially, for a drone, explosives, and other weapons of mass destruction that would be used to carry out an attack,” federal investigators said in their affidavit.

According to the affidavit, “Other Parties, with whom Casap had been in contact, appeared to be aware of his plans and actions and to have assisted Casap in executing them.”

Casap appeared in court for a preliminary hearing regarding his charges. Casap has not yet entered a plea and is still in custody. According to the Waukesha County court docket, his next court appearance will be for an arraignment in May.
