Nikita Casap Case
The Village of Waukesha man accused of killing his mother and stepfather in their Cider Hills home last February was convicted of two counts of first-degree intentional homicide on Thursday after entering guilty pleas to those charges against him.
As a result of a plea agreement, the state agreed to dismiss the remaining two counts of hiding a corpse, two counts of theft, operating a vehicle without consent, and two counts of ID theft against him.
Nikita Casap, 18, was charged after authorities discovered the bodies of his mother, Tatiana Casap, 35, and stepfather, Donald Mayer, 51, who were believed to have been killed some time around Feb. 11. He was arrested on Feb. 28 in WaKeeney, Kansas, driving his stepfather’s Volkswagen Atlas, in possession of a .357 Magnum missing from the residence, as well as $14,000 in cash, and jewelry, according to a criminal complaint.
Casap faces life in prison when he is sentenced March 5, although the state and defense can argue as to whether he should be eligible for extended supervision after serving 20 years on each count.
Nikita Casap replied, “Yes, your honor” as Circuit Court Judge Ralph Ramirez asked him if he understood the trial rights he was waiving with his pleas.
After court, District Attorney Lesli Boese said she felt it was significant that Casap accepted responsibility for the murders and spared the victims’ families the experience of a trial in the matter. She added that she did not believe he should ever get an opportunity to be released to the community.
“I think this is a maximum penalty case. I assume that’s what I will be arguing. I never thought anything other than that from the time I charged this case,” Boese said. “Certainly I don’t think he should be out in the community and I would argue against it. … I believe he is a danger to the community.”
Boese said the families of the victims agreed with how the case was resolved. Boese added she was “a little surprised” that Casap entered the pleas.
“I mean, there is really no down side for him to take it to trial but, again, I think the courts look at the fact that someone takes responsibility for what they did and I think that’s a factor that they consider at sentencing,” she said. The criminal complaint in the case said authorities believe the last time either parent was seen alive was Feb. 11, 2025, the date it was believed they were killed. After Mayer’s mother contacted authorities for a well-being check of her son’s home, deputies noted “an odor of decay” and found Tatiana Casap’s body in a hallway under a blanket. Returning with a search warrant, deputies found Mayer’s body in a first-floor office with a gunshot wound to the back of his head, the complaint said.
Nikita Casap was arrested following a traffic stop in WaKeeney, Kansas, with a .357 Magnum believed to have been missing from the residence, as well as ammunition consistent with bullet casings found at the scene, the complaint said. Police also found in his car more than $14,000 in $100 bills, $14,000 in jewelry as well as 14 electronic devices, including a security camera. The camera had footage on it of the office where Mayer’s body was found, showing Casap going into the room Feb. 16 through 22 to keep candles lit near the deceased body, and at one time Feb. 20, Casap is heard saying, “So you can see him there. I can literally see the (expletive) rotten body there,” the complaint said.
The complaint indicates a review of Nikita Casap’s phone showed a Jan. 29 message that included him asking someone, “How long will I need to hide before I will be moved to Ukraine? One to two months?” Casap told that person, “I should probably brush up on my Russian, because I can understand just fine but speaking is harder.” In another Telegram thread with an unknown person, Casap asks, “So while in Ukraine, I’ll be able to live a normal life? Even if when it’s found out I did it?”
The complaint said Nikita Casap appeared to have used his stepfather’s bank debit card between Feb. 12 and Feb. 28, at numerous places in Waukesha, as well as Illinois, Iowa, Nebraska, Wyoming and Colorado.
Prosecutors also contemplated but did not formally charge with intimidating a witness after a schoolmate reported conversations she had with him. The girl said Casap told her he “was planning to kill his parents and then himself so they do not have to live without him. Witness A told the defendant that was not okay, and the defendant then told her not to worry because he was not going to follow through on it,” the complaint said. “The defendant further told Witness A if anyone found out what he told her, that something bad was going to happen to her or in his words, ‘It wouldn’t end well’ for her” in a conversation that took place last December and into January, the complaint said.
The girl told a detective Nikita Casap “had told her he was in contact with a male in Russia through the Telegram app, and they were planning to overthrow the U.S. government and assassinate President Trump. The girl reported telling Casap he sounded like a neo-Nazi and he sounded like a school shooter,” and it made her feel extremely uncomfortable, the complaint said.
According a search warrant of electronics of Nikita Casap’s held by the county Sheriff’s Department filed in federal court, a phone search revealed images and communications referencing a self-described manifesto regarding assassinating the president, making bombs, and terrorist attacks. FBI agents found images of a three-page document titled “Accelerate the Collapse” calling for the assassination of Trump with the mission to start a political revolution in the United States and “save the white race” from “Jewish controlled politicians.”
The documents said, “Casap appears to have written a manifesto calling for the assassination of the President of the United States. He 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.”
A spokesman for the U.S. Department of Justice said Thursday, “Pursuant to the longstanding polices of the Department of Justice, we do not comment or provide information on matters that are outside of the public record or that would confirm or deny the existence of any federal investigation.”
Nikita Casap also is named in a Waukesha County probate case involving the estate of his mother, where he is listed currently as heir. That matter remains pending but Wisconsin law bars the beneficiary of any estate from receiving benefits if that person was the one who caused the decedent’s death.

Nikita Casap Sentencing
A Wisconsin man who killed his parents and stole their money to fund his plan to kill President Trump with a bomb dropped from a drone was sentenced to life in prison on Thursday.
Nikita Casap, 18, pleaded guilty in January to two counts of first-degree intentional homicide in Waukesha County Circuit Court in connection with the shooting deaths of his mother, Tatiana Casap, and stepfather, Donald Mayer, in 2025. Prosecutors dropped seven other charges in a plea deal, including two counts of hiding a corpse and theft.
First-degree intentional homicide carries a mandatory life sentence. The only question as Judge Ralph Ramirez began the sentencing hearing Thursday afternoon was whether he would make Casap eligible for parole at some point.
Calling Casap’s offenses “horrific” and “inexplicable,” Ramirez ultimately handed down two life sentences with no chance at extended supervision, the term the Wisconsin criminal justice system uses for parole. The judge said he didn’t have a “crystal ball” that would tell him when Casap would change, if ever.
“I choose to find he’s not eligible for extended release because I do not know … when and if and whether a profound and significant change can occur,” Ramirez said
According to a criminal complaint, investigators believe Nikita Casap shot his stepfather and mother at their home in the village of Waukesha on or around Feb. 11, 2025.
He lived with the decomposing bodies for two weeks before fleeing across the country in his stepfather’s SUV with $14,000 in cash, jewelry, passports, his stepfather’s gun and the family dog, according to the complaint. He was eventually arrested during a traffic stop in Kansas on Feb. 28 after four days on the run.
Federal authorities have accused Nikita Casap of planning his parents’ murders, buying a drone and explosives and sharing his plans with others, including a Russian speaker. They said in a federal search warrant that he wrote a manifesto calling for Trump’s assassination and was in touch with others about his plot to overthrow the U.S. government
“The killing of his parents appeared to be an effort to obtain the financial means and autonomy necessary to carrying out his plan,” that warrant said.
Detectives found several messages on Casap’s cellphone from January 2025 in which Casap asks how long he will have to hide before he is relocated to Ukraine. An unknown individual responded in Russian, the complaint said, but the document doesn’t say what that person told Casap. In another message Casap asks: “So while in Ukraine, I’ll be able to live a normal life? Even if it’s found out I did it?”
Dist. Atty. Lesli Boese told the judge Thursday that Casap was too dangerous to ever be released from prison.
Pulling from an interview Nikita Casap gave to the FBI, Boese said that Casap and his mother moved to the United States from the Republic of Moldova when Casap was a grade-schooler but he became increasingly addicted to what she called “disturbing websites” as he grew older. She didn’t elaborate but at one point said he had been researching serial killers and school shootings.
Boese said Nikita Casap developed a plan in late 2024 to target Trump with an AK-47 rifle attached to a drone. The teen later decided he wanted to drop explosives on Trump from a drone and then flee by ship to Ukraine, where he planned to hide for a decade, according to the district attorney. Casap told agents he wouldn’t have cared how many people around Trump got hurt during the assassination attempt.
Nikita Casap started talking with two people online who offered to sell him the drone and the explosives. He sent one of them $8,700 in bitcoin from his stepfather Mayer’s account without realizing they were scamming him and there was never a drone or any explosives, Boese said.
“He walked right into it,” she said.
Casap’s attorney, Paul Rifelj, asked Ramirez to make Casap eligible for parole after 20 years. He said that news of a doctor who drove his car into a Christmas market in Magdeburg, Germany, in December 2024 sent Casap into a rage. The teen decided then that he wanted to change the world by killing a politician, Rifelj said.
The two contacts who promised to help him kill Trump convinced him that he was part of a larger military strategy, offering him direction and purpose at a time when he was becoming isolated at school, according to Rifelj.
“Children are more than their worst deeds,” he said.
Nikita Casap appeared to tremble as he listened to both sides make their cases. He gave a tearful speech, saying that he loved his mother and he was worried about her all the time, even when she was reaching for something on a high shelf. He said he wasn’t as close with Mayer, but Mayer still treated him like a son.
But he became obsessed with hateful thoughts.
“I thought I was part of a revolution,” he said. “I thought I was part of a war. I told myself bad things had to happen.
