Father of girl charged in Slenderman stabbing testifies as attorneys work to get her confession thrown out

WAUKESHA COUNTY -- The father of one of the girls charged in the so-called "Slenderman" stabbing case testified in court on Thursday, December 22nd. Anissa Weier was in court as her attorneys argued her confession to the crime, made when she was just 12 years old thrown out.

This complex case stems from May 2014 when Weier and Morgan Geyser, then-12-year-old girls allegedly stabbed their friend 19 times to please the internet horror character Slenderman. Both Geyser and Weier are 15 years old now. They're charged as adults -- each facing one count of attempted first degree intentional homicide, as party to a crime, use of a dangerous weapon.

Weier's father William told the court how he was kept away from his daughter while Waukesha police detectives questioned her about the stabbing in May of 2014.

The video in question shows Weier sitting in a room, waiving her rights to have counsel and to remain silent.

A detective tells the girl: "I'm going to read those rights to you, OK? The main point is I still don't know what happened and I need to know that today."

William Weier testified that detectives wouldn't let him see his daughter until hours after she was questioned. During that time, she willingly talked to police.

"Not only Anissa, but all four of my children were taught to trust the police department. If you find yourself in trouble or in danger, find a firefighter, find a police officer. They are there to help you," William Weier said.

William Weier said his daughter was not delusional when she waived her Miranda rights.

"Why would any parent discuss with a 12-year-old what Miranda rights mean?" William Weier said.

"The parents were trying to get to their child and were prevented. When they learned there was something serious alleged against their child, they wanted to go to her. They tried to go to her and they were prevented from seeing her -- and very few parents understand with a child under 18 if law enforcement wants to question them they will," Weier's attorney said.

Weier's attorney said other states have laws requiring children to be represented by counsel when questioned. Wisconsin does not.

The judge will make his decision at a later date.

A judge recently ruled the two girls will be tried separately. Those trials are likely to begin in spring.
