Prosecutors say their son, 17-year-old Nikita Casap, shot and killed his parents more than two weeks earlier. They say he fantasized about killing his parents and himself. Prosecutors also say Casap had been in contact with a Russian speaker with a plan to try to flee to Ukraine before taking money, passports, a car and the family dog.

Inside the family home on Cider Hills Drive, prosecutors said Donald and Tatiana Mayer had been dead for days. Court filings say footage from a surveillance camera showed a camera trained on Donald Mayer's body, covered by blankets and pillows.
The complaint says Nikita is seen entering the room to "keep candles lit." At one point, Nikita grabbed the camera and turned it around. He is heard saying, "So you can see him there. I can literally see the (expletive) rotten body there."
Court filings say investigators believe Casap killed his parents sometime on Feb. 11. But Casap did not leave Waukesha until Feb. 23. That is when he traveled through Illinois, Iowa, Nebraska, Wyoming and Colorado before getting arrested in rural northwestern Kansas. He was in his parents' SUV.

Filings say investigators found telegram messages in the days and weeks before the homicides between Casap and a Russian speaker. Casap asked, "…while in Ukraine, I'll be able to live a normal life? Even when it's found out I did it."
