Robbie Mueller's attorney filed a motion to suppress statements the defendant made "as a result of an illegal interrogation" on July 29, 2010 regarding the death of Sidnee Stephens.
Mueller is currently charged with four counts of first degree murder, one count of aggravated kidnapping, two counts of home invasion, one count of residential burglary, one count of kidnapping and one count of concealment of a homicide death.
The motion, filed Aug. 16 by Charles H. Stegmeyer, states that "on July 29, 2010, the defendant, then 15 years old, and his mother, Rhonda Mueller, at the request of the Pinckneyville Police department, went to the station for an interview. At two separate times during the interrogation, defendant's mother raised the issue of needing an attorney. At first she asked if she needed to get an attorney and was then told by the juvenile police officer that it 'was her prerogative.' The police, used coercive tactics by ensuring Rhonda Mueller that all they wanted was the truth and continued to question the defendant. As the interview continued Rhonda Mueller told the officers that 'a (referring to defendant) 15-year-old boy needs to be sitting with an attorney.' The police, again using coercive tactics, ignored the request for an attorney and continued interrogating the defendant."
A hearing on the motion to suppress all statements, admission and confessions made by the defendant during questioning will be held at 9 a.m. on Aug. 23 before Judge Richard Aguirre.
Two other Pinckneyville teens were charged in the murder of Sidnee Stephens. Carl Dane pleaded guilty and was sentenced to 60 years in prison. He then committed suicide in Perry County Jail the night before he was to be transferred to the Illinois Department of Corrections.
James Glazier was found guilty in a stipulated bench trial July 30. He is to be sentenced Sept. 13 in Perry County Court. Both the prosecution and defense have agreed to a 60 year sentence.
