Taylor Schabusiness to be sentenced Tuesday in dismemberment death of Shad Thyrion

GREEN BAY - Taylor Schabusiness is scheduled to be sentenced Tuesday for the brutal murder of Shad Thyrion in February 2022.

Thyrion, 24, of Green Bay, was killed and decapitated in the basement of his mother's home. Schabusiness was arrested and charged in his death and dismemberment.

Schabusiness, of Green Bay, pleaded not guilty and not guilty by reason of mental disease or defect.

A Brown County jury found Schabusiness, 25, guilty of killing Thyrion, third-degree sexual abuse, and mutilating his corpse in July. In the second part of her trial, the jury found that she did not suffer from mental disease or defect when she killed Thyrion.

The case has attracted international attention. Over one and a half years later, Schabusiness will get sentenced Tuesday. Here's what you need to know before the sentencing.

Schabusiness arrested in Thyrion's killing, decapitation

Schabusiness was charged for Thyrion's death and dismemberment after Thyrion's mother found her son's head in a bucket in the basement. Thyrion had been strangled and decapitated on Feb. 23, 2022, in the west-side house he lived in with his mother.

Schabusiness was arrested in February 2022. She was charged with first-degree intentional homicide, third-degree sexual assault, and mutilating Thyrion's corpse. She and Thyrion had been friends.

Schabusiness' competency is questioned

Schabusiness' mental state was questioned in several hearings during the case. Mental health evaluations were ordered for Schabusiness to determine if she was fit to stand trial.

She was ultimately found mentally competent to assist in her own defense and a trial was scheduled for July 2023, though questions about her mental health continued.

She had entered a plea of not guilty by mental disease or defect in September 2022.

Schabusiness is convicted of Thyrion's killing, dismemberment

Following a three-day trial, a Brown County jury deliberated for 50 minutes and found Schabusiness was guilty on all counts July 26.

Because Schabusiness entered the mental order defense, the trial then moved to the second phase to determine if Schabusiness was not guilty due to mental disease or defect.

"This is bizarre. This is strange. This is unnatural, but in no way is it unclear," Brown County District Attorney David Lasee said during closing arguments. Schabusiness "did cause Shad Thyrion's death."

Schabusiness could spend life in prison

In the second part of the trial, jurors listened to psychologists who testified about Schabusiness' mental state at the time of the Thyrion's murder. She waived her right to testify during both parts of the trial.

They were to determine if Schabusiness would spend the rest of her life in prison or at a mental health facility.

On July 27, the jury found that she did not suffer from mental disease or defect when she killed Thyrion.

She faces a mandatory life sentence but the judge could determine if there is a possibility of parole.

She will be sentenced Tuesday morning.
