MADISON, Wis. -

A Sun Prairie man accused of decapitating his mother with a large sword will remain in an institution.

Matthew Skalitzky, 41, was charged with first-degree intentional homicide in the Sept. 11, 2015 death of 68-year-old Jane Skalitzky. He was found incompetent to stand trial and was sentenced Friday to remain confined in an institution.

Prosecutors and defense attorneys agreed that Skalitzky is not ready for conditional release. The family said they hope he will remain confined for the rest of his life and take his medication.

"(The) level of compassion and forgiveness (Skalitzky's) family has shown has been remarkable," Assistant DA Corey Stephan said.

Skalitzky’s defense said he had a long history of mental issues, and he is now taking his medication and he realizes the gravity of what happened.

"Speaking on behalf of Matthew, he too, now that he's stabilized and has taken his medication, understands the grave nature of his situation and what has occurred," Skalitzky's attorney Stanley Woodard said. "He'll have to live with that. But he's willing to deal with that and deal with that as ordered by the court."

Skalizky's father said it's been a difficult year.

"I have gone through more than anyone should ever have to endure. I not only lost my wife, but I lost my son," Joe Skalizky said. "Both of these losses were preventable. Mental illness is real and needs to be taken seriously."

"Jane was dedicated unconditionally to advocating for Matt, which she did up until her very last breath," he said.

Joe Skalizky said the system is broken.

"Family members are put in a situation where they must care for the individual yet have minimal rights to get the help needed. How was Jane supposed to force medication Matt believed he did not need? How was Jane supposed to seek inpatient care for him when it was voluntary?"

Dane County Judge Josann Reynolds said Skalitzky will need to remain in institution because he poses a significant risk of bodily harm to himself or others without psychotropic medications. He will be required to take his medications involuntarily.
