WAUKESHA, Wis. (CN) - A Wisconsin teenager pled not guilty on Wednesday to charges related to the murder of his mother and stepfather as part of a plot that was supposed to end with the assassination of President Donald Trump and a coup of the U.S. government.

Nikita Casap, 18, is charged with two counts of first degree intentional homicide and two counts of hiding a corpse, two counts of theft of moveable property, operating a motor vehicle without owner's consent, two counts of identity theft for financial gain and intimidating a witness.

Police say they discovered Casap's mother and stepfather dead in their home on February 28 while conducting a wellness check requested by Casap's school and his grandmother. Tatiana Casap and Donald Mayer appeared to have been dead for nearly two weeks when they were found, according to the state.

On Wednesday, Casap pled not guilty to all charges against him, including the most recently added charge of intimidating a witness - brought after it came out that he had told a classmate about his criminal plans, but that "it wouldn't end well" for her if she reported him to the police.

The court raised his bail to $1 million at his initial appearance in March with the addition of the 10th felony charge.

Casap is represented by attorneys Paul Rifelj and Kathryn Holtz, who took over the case just one week prior to Wednesday's arraignment. Rifelj asked for additional time to review discovery, which he only received in court that day.

Victims and witnesses appeared anonymously via zoom, and their identities will remain anonymous until trial, according to Waukesha County District Attorney Lesli Boese.

Police arrested Casap on February 28. He was driving his stepfather's 2018 Volkswagen Atlas, and had his mother's bank card, over $6,000 worth of her jewelry, $14,000 in cash and his stepfather's gun in his possession.

One of his classmates, who is only referred to as "Witness A" in the state's complaint, told police that Casap had a crush on her and they communicated on Snapchat regularly. Casap apparently gave her recommendations for Russian artists, "fascist activists", "homo fascism" and "gore edits."

According to police, Casap also told the witness that he and a Russian man he had been communicating with on Telegram were planning to overthrow the U.S. government and assassinate Trump. The plan, according to text messages included in the complaint, was that the unknown Russian man would help move Casap to Ukraine after the assassination.  

Boese says her office is not coordinating with the FBI. No federal charges have been filed, and the FBI could not be immediately reached for comment.

Casap was also holding a memory card when he was arrested, which contained video from the scene. The video was taken in Casap's stepfather's office, where his body was found. The footage shows Casap regularly entering the room to keep candles lit near his deceased body, which was next to the desk and covered in blankets, according to the state.

At one point on February 20, Casap bent over and turned the camera to face him to say "So, you can see him there. I can literally see the fucking rotten body there," the state claims.

Casap apparently did not return to school after February 11, the estimated time of death of his parents. Teachers reportedly reached out to check on him, to which he responded that he had become sick.

According to the state, Casap shot his stepfather in the back of the head in the office, and his mother in the kitchen. She was still wearing her winter coat, and her body was blacked with decomposition.

Casap did not stay in the Waukesha area.  He was first seen walking his dog at an Iowa truck stop after the wellness check was performed at his home. Later, he was pulled over in Kansas where the car was taken into custody.

Casap will appear in court again on August 18 to set a trial date.
