A Wisconsin teenager charged with killing his parents was planning to assassinate President Donald Trump as part of a plot to overthrow the government, according to an FBI affidavit unsealed Sunday.

The 17-year-old, Nikita Casap, faces two counts of first-degree murder, two counts of hiding a corpse, theft and other charges in connection with the deaths of his mother, Tatiana Casap, and his stepfather, Donald Mayer.

Federal authorities who reviewed the teenager’s communications allege that he killed them to “obtain the financial means and autonomy necessary” to carry out his plans to kill the president in order to destabilise the US government and “save the white race.”

Officials found a three-page antisemitic manifesto that praised Adolf Hitler and had bombmaking instructions. They also found messages in Russian and communications on TikTok and Telegram, a messaging app, in which he detailed a plot to kill his parents as well as proclaim his allegiance to neo-Nazi, racially-motivated extremist groups.

The bodies of his mother and stepfather were found in advanced decomposition in the family’s home in Waukesha, a Milwaukee suburb, on February 28 after Donald Mayer’s mother requested a welfare check on the residence. School officers at Waukesha West High School had also requested a welfare check after Casap had missed school for about two weeks.

Authorities believe Casap shot and killed his parents and lived with their corpses for weeks before running away with Mr Mayer’s SUV, about $14,000, passports, phones, his parents’ wallets, a firearm and the family dog. The teenager was arrested during a traffic stop in Kansas soon after his parents’ bodies were found.

Casap is in custody and on a $US1 million ($1.6m) bond at the Waukesha County jail and is due in court next month to enter a plea.

According to the affidavit, Casap “was in touch with other parties about his plan to kill the President and overthrow the Government of the United States. And he paid for, at least in part, a drone and explosives to be used as a weapon of mass destruction to commit an attack.”

“The killing of his parents appeared to be an effort to obtain the financial means and autonomy necessary to carrying out his plan. Other parties, with whom Casap was in contact, appear to have been aware of his plans and actions and to have provided assistance to Casap in carrying them out,” authorities wrote.

According to the affidavit, the teenager shared his plans to kill his parents with a classmate. He also told a classmate that he was in contact with a man in Russia about plans to assassinate Mr Trump and overthrow the government.

A review of Casap’s communications also found that he planned on leaving the United States for Ukraine after carrying out his plot.

The FBI in Milwaukee referred questions to the US attorney’s office in the Eastern District of Wisconsin, which declined to comment on the case.

Casap’s public defender, Nicole Ostrowski, did not immediately respond to a phone call seeking comment on the case. The White House did not immediately respond to a request for comment.
