People v. Shanklin

Defendant was convicted, after jury trial, of first-degree murder, home invasion, and aggravated criminal sexual assault.Court properly held Frye hearing and determined that GSS (Gudjonsson Suggestibility Scale) method of testing for susceptibility to interrogation techniques did not meet Frye standard for reliability and admissibility. Court properly denied Defendant's motion to suppress, as Defendant did not exhibit signs of severe heroin withdrawal that would render his statement unknowing and involuntary.(LAMPKIN and REYES, concurring.)
