Nikita Casap in court

A teen charged in the deaths of his mom and stepfather is due in court Monday.

WAUKESHA, Wis. - The Waukesha teen charged in connection with the deaths of his mother and stepfather appeared in court for a status hearing on Monday, Aug. 18. 

During the hearing, the defense requested the matter be adjourned for further proceedings. The court adjourned the matter. Casap is due back in court on Oct. 2.

He pleaded not guilty to the charges against him back in May. 

New charge filed

What they're saying:

Nikita Casap was previously charged with two counts of first-degree intentional homicide, two counts of hiding a corpse and more. With his new defense attorney by his side, the 17-year-old learned of a new charge on May 7: intimidation of a witness.

Waukesha County District Attorney Lesli Boese said the new charge stems from what Casap's classmate at Waukesha West High School told police.

The student said Casap added her on Snapchat prior to the death of his parents. The girl said Casap sent her "gore edits," which she explained were flashing sequences of war and horror set to Russian music.

The girl said Casap told her how he wanted to die by suicide and that despite a "happy childhood," he was planning to kill his parents. Casap allegedly told the girl, if anyone ever found out what he said to her, "it wouldn't end well."

Federal investigators said Casap plotted to assassinate President Donald Trump. The FBI believes Casap wanted his parents' money to "start a political revolution in the United States" and "save the white race."
