GALESBURG – A man accused of killing eight people in Illinois and Missouri won't face a second trial for aggravated battery after the case against him was dismissed.

Nicholas Sheley (SHEE'-lee) is accused of killing eight people in 2008. He's been convicted of killing a 65-year-old Galesburg man, and his second murder trial is scheduled for September.

In the battery case, Sheley was sentenced to seven years in prison after prosecutors accused him of dismantling a Knox County jail chair and throwing its legs at a guard. An appeals court, however, ruled the trial court erred in finding Sheley suffered from a "severe mental illness" that prevented him from preparing his own defense.
