GREEN BAY - Accused killer Taylor Schabusiness began to use drugs when she was in fifth grade, imagined she was in a relationship with mass killer Jeffrey Dahmer and appeared to show signs she has "an active psychotic disorder" a psychologist testified Thursday in Brown County Circuit Court.

Diane Lytton, a forensic psychologist who examined the 25-year-old Green Bay woman at the request of her former defense lawyer, Quinn Jolly, and current defense lawyer, Christopher Froelich, told the court she believes Schabusiness is not fit to stand trial on charges she killed and sexually abused her friend, Shad Thyrion, 24, of Green Bay, after the pair had sex in the basement of the house Thyrion shared with his mother.

"Sometimes she seemed coherent and lucid," Lytton told Judge Tomas Walsh in court for an evidentiary hearing, but "sometimes she would stand up and scream. Sometimes she would hit her head." Lytton said Schabusiness has previously been prescribed anti-psychotic medication, but admitted to an evaluator that she would stop taking it.

Thursday was the first time there had been testimony from a psychologist who found Schabusiness was incapable of assisting in her own defense. A psychologist who had evaluated the woman on behalf of Caleb Saunders, a Brown County assistant district attorney prosecuting the case, had concluded in 2022 Schabusiness was fit to stand trial.

Walsh did not rule Thursday on whether Schabusiness can stand trial. He indicated after the hearing that he expects to hear testimony from a prosecution psychologist before he rules whether Schabusiness can go to trial. A jury is scheduled to be selected July 21, with a trial beginning at 8:30 a.m. July 24.
