MADISON, Wis. -- A 31-year-old woman accused of killing her mother in Blue Mounds on April 14 entered a not guilty by reason of insanity plea/guilty insanity plea on Tuesday, online court records show. The prosecution did not object to the plea.

Sierra Schoonover was charged with first-degree intentional homicide by use of a dangerous weapon. Previously, the charge had a domestic abuse enhancer but was been dropped Thursday.

The court accepted Schoonover's plea and adjudged her to be guilty.

Sierra's mother was found dead in April at a home in the 10800 block of Smokey Mountain Trail.
