Wisconsin Teen Charged in Double Homicide of Mother and Stepfather

Prosecutors allege Nikita Casap, 17, lived with the bodies for nearly two weeks before fleeing the state; bail set at $1 million.

Nikita Casap, 17, faces charges including two counts of first-degree intentional homicide for the February killings of his mother, Tatiana Casap, and stepfather, Donald Mayer, in Waukesha, Wisconsin.
Prosecutors claim Casap lived with the decomposing bodies for nearly two weeks, attending school and using his stepfather’s accounts to communicate with others before fleeing on February 24, 2025.
Authorities discovered video evidence showing Casap lighting candles near his stepfather’s corpse and communicating about plans to flee to Ukraine and assassinate Donald Trump.
Casap was arrested in Kansas on February 28, 2025, during a traffic stop, where police found a firearm matching the murder weapon and other incriminating evidence in his stepfather’s car.
His preliminary hearing is scheduled for April 9, 2025, as prosecutors continue to present disturbing evidence, including video recordings and digital communications.
