Sheley is charged with kidnapping 65-year-old Ronald Randall, hijacking his truck, stealing his wallet and killing him on June 28 in Galesburg.

The Knox County state's attorney's office wouldn't comment on when a decision might be made on whether to seek the death penalty.

Police suspect Sheley also bludgeoned seven other people to death in Illinois and Missouri in late June. He's been charged in three of those deaths.

A pretrial hearing is set for October 6.
