Milwaukee-area firm to be featured in Slender Man documentary


A Wisconsin trial-consulting firm will be featured in a documentary that premieres this weekend.

Hartland-based Rosenberg Consulting Services President Rob Rosenberg will be featured in a two-hour documentary titled “Slender Man Stabbing: The Untold Story.” It premieres Saturday at 7 p.m. on the REELZ channel and was produced by Dorsey Pictures.

REELZ is a cable and satellite network that focuses on programs related to celebrities and national news.

The documentary explores the case of two 12-year-old Wisconsin girls, Morgan Geyser and Anissa Weier, who in May 2014 lured a friend, Payton Luetner, into a Waukesha park and stabbed her 19 times in order to appease a fictional character called Slender Man.

RCS, which specializes in courtroom technology and trial graphics, was part of Geyser’s defense team. Geyser pleaded guilty to attempted first-degree homicide and was sentenced last year to 40 years in a mental hospital. She recently filed an appeal. Weier was sentenced to a mental hospital for 25 years.

Filmmakers interviewed Rosenberg about his firm’s work on the case. RCS, Rosenberg and his team used a technique called Wizpor, which was created by Trial Consultant Amy Singer and involves doing mock trials and tailoring attorneys’ arguments using advice from online focus groups.
