FBI documents: Waukesha teen accused of double homicide also plotted to assassinate Trump

(WLUK) -- A Wisconsin teenager accused of murdering his mother and stepfather was also plotting to assassinate President Donald Trump, according to federal court documents obtained by WITI-TV.

Nikita Casap, 17, allegedly killed his mother, Tatiana Casap, and stepfather, Donald Mayer, at their Waukesha home in February. Days later, Casap was arrested in Kansas, driving Mayer's stolen vehicle and with a gun in his possession.

Law enforcement seized and searched Casap's cellphone and other electronic devices as part of their investigation into the double homicide. A search warrant, filed with the U.S. District Court for the Eastern District of Wisconsin, outlined the discovery of a conspiracy to assassinate Trump in an effort to start a "political revolution."

According to WITI, investigators uncovered material on Casap's phone related to "The Order of Nine Angels" -- described by the FBI as a "satanic cult" with "strong anti-Judiac, anti-Christian and anti-Western ideologies" that claims to "incite chaos and violence."

Court documents also say Casap paid for, at least in part, "a drone and explosives to be used as a weapon of mass destruction to commit an attack." The warrant states Casap's alleged killings of his mother and stepfather "appeared to be an effort to obtain the financial means and autonomy necessary" to carry out the plan.

WITI reports that further investigation into Casap's phone unveiled months worth of images, planning and communication regarding a "self-described manifesto regarding assassinating the president, making bombs, and terrorist attacks." Other people reportedly encouraged and helped Casap in the process.

Investigators also found images of a three-page document titled "Accelerate the Collapse." It appeared to be the manifesto referenced in the messages that called for the president's assassination with the goal of starting "a political revolution in the United States" and "save the white race" from "Jewish controlled" politicians. The document contained images of Adolf Hitler with the text "HAIL HITLER HAIL THE WHITE RACE HAIL VICTORY.

WITI says an excerpt from that document specifically referenced Trump, saying "getting rid of the president and perhaps the vice president" is "guaranteed to bring in some chaos." Another excerpt from the document added, "Point being this manifesto is specifically for the attack that targets Trump."

The federal search warrant obtained by WITI says authorities interviewed one of Casap's classmates, who said Casap planned to kill his parents but he didn't have access to a gun.

"The classmate also said Casap said he was in contact with someone in Russia and was "planning to overthrow the government of the United States and assassinate President Trump,'" the classmate told police.
