Jury to Hear Mental Illness Claim during Slender Man Trial

September 06, 2017 11:37 AM

Jury selection is underway in the trial of a 15-year-old girl who has pleaded guilty to second-degree attempted intentional homicide for stabbing her friend as a sacrifice to the fictional boogey man Slender Man in Waukesha, Wisconsin.

ABC-affiliate WISN reports jurors will decide next week whether Anissa Weier was mentally ill when she stabbed Payton Leutner 19 times more than three years ago and whether Weier is legally responsible for the crime.

The jury will be made up of 16 people with four alternates, and the pool of jurors attorneys are selecting from is as large as 150 people. WISN reports 40 or so jurors were excused after attorneys on both sides of the case objected.

The trial is expected to last two weeks and begin Monday. If Weier is found legally guilty for the crime, she faces 10 years in prison. If not, she will spend three years at a mental hospital.

The second girl involved in the case, Morgan Geyser, will have a separate trial, which is slated for October.
