After deliberating for less than two hours, a jury of seven men and five women found Michael D. Wilhelm guilty on all 10 felony counts, for raping or sexually abusing three girls seven years ago. He will be sentenced to mandatory life in prison, as a result of the guilty verdicts on two of the counts of predatory criminal sexual assault of a child, two separate victims, both of whom were younger than 13. A sentencing hearing will be October 18. Wilhelm, 40, who has been held in jail since his arrest in August 2015, showed no emotion as Associate Macon County Judge Jeffrey Geisler read the verdicts at 1:55 p.m. Wednesday. It was a difficult, emotionally charged trial, which began on Monday with a full day of jury selection and featured testimony from six women who told their stories of being sexually assaulted or abused by Wilhelm when they were children.
