"I was in the process of joining the National Honors Society as well," Casap said.

But when detectives asked Casap about the February 2025 deaths of his mother and stepfather, the then 17-year-old shut down. 

"I think I’d rather first talk with an attorney," Casap said.

Tatiana Casap and Donald Mayer

For the first time, we are seeing inside Casap's home. Investigators say he shot and killed his parents, Tatiana Casap, and Donald Mayer, and hid their bodies under blankets. 

Bullet holes are marked on the wall and floor. Candles were placed near the victim's decomposing bodies. 

After staying with the bodies for days, investigators say Casap went on the run in his parents' SUV. He drove across the country, and was pulled over about two weeks later in Kansas. Casap had jewelry, cash, ammunition and weapons in the vehicle. 

Guilty plea entered

What's next:

Earlier this month, Casap changed his plea to guilty in Waukesha County court. He will be sentenced in March. First degree intentional homicide charges carry mandatory life sentences.
