WAUKESHA, Wis. (CBS 58) -- A judge has ordered Morgan Geyser to the maximum commitment of 40 years in the Slender Man stabbing case. 

This is a developing story. Stay tuned for updates from CBS 58 on air and online. 


WAUKESHA, Wis. (CBS 58) – A Waukesha County judge still needs to hear more testimony before deciding the fate of a teenager involved in the Slender Man stabbing case.

15-year-old Morgan Geyser is facing a maximum commitment of 40 years in a mental hospital.

Prosecutors are arguing for that.

The stabbing happened when Morgan Geyser was 12 years old. She pleaded guilty to stabbing her friend in the woods 19 times, planning the attack for months with another then 12-year-old girl, Anissa Weier. Weier also pleaded guilty in the case and was committed to a mental institution for 25 years in December.

Two doctors have testified so far Thursday morning. The first was Dr. Brooke Lundbohm who evaluated Geyser multiple times since the crime, but most recently three months ago. She says some of the reason she doesn’t recommend Geyser’s conditional release is because she’s still experiencing symptoms, including a voice she calls Maggie.

“She’s saying she still hears that voice periodically. It’s less intense, less frequent and that's the same report she provided to me in October while we were meeting for this evaluation and mentioned she last heard that voice of Maggie a few weeks prior to when we were meeting,” Dr. Lundbohm said Thursday.

The doctor the defense called to the stand disputes that information, saying the voice of Maggie is gone and Morgan doesn’t have current psychotic symptoms.

State witnesses have already testified. Before the judge can make a decision, there will be testimony from more defense witnesses and arguments from each side.
