People v. Barker
Illinois Appellate Court
Criminal Court
Experts
Evidence
Defendant was convicted of first degree murder and aggravated criminal sexual assault, and petitioned the court, under Section 116-3 of Illinois Code of Criminal Procedure, to conduct fingerprint or forensic testing. Court denied petition, finding that evidence had already been subjected to adequate DNA testing. Court properly denied petition, as Defendant failed to show how Y-STR DNA testing would have the potential to produce new, noncumulative evidence materially relevant to his assertion of actual evidence, as Y-STR testing cannot establish who the singular contributor of a crime scene source is, and is not as compelling as an STR profile. Defendant failed to satisfy requirement of Section 116-3 that the tests requested in the petition were not scientifically available at time of trial; the tests Defendant requested on appeal and those requested in original motion had all been judicially recognized as generally accepted by relevant scientific community at time of trial. (TOOMIN and LAVIN, concurring.)
