A man who killed his Sun Prairie neighbor with a sword won't be getting out of a mental health institution.

Zacahary Schams and his lawyer petitioned for his release from Mendota Mental Health Institution. Schams was given a lifetime commitment to Mendota after he was found not guilty by reason of mental illness in the 2009 death of 31-year-old Anthony Edlbeck.

The victim's family attended a hearing Monday in Dane County Circuit Court. Edlbeck's father, Dale, told the judge they were fearful Schams could commit other violent acts if he's released.

The State Journal (http://bit.ly/11PTrPJ ) reports Schams' public defender, Dennis Burke, conceded there wasn't enough evidence to support the release petition.
