(MCT) — Prosecutors said Wednesday that they are preparing for two of Will County's biggest criminal trials in years to overlap this summer, with both Drew Peterson and Christopher Vaughn scheduled to face a jury in adjoining rooms at the Joliet courthouse.

Peterson, the former Bolingbrook police sergeant accused of drowning his third wife, is scheduled to go on trial July 30, with jury selection taking up the week prior. Vaughn's jury selection is scheduled to start Aug. 13. He is accused of shooting to death his wife and three children in the family's SUV on the way to a Springfield water park.
