A new murder trial will be held for Kenneth Baumruk, the man convicted once of killing his wife in a shooting at the St. Louis County Courthouse. He also wounded several other people before he was stopped by gunshots fromsecurity guards. The State Supreme Court has thrown out his first conviction because the trial was held in the same courthouse in which the shootings took place. The county prosecutor had the choice of calling a new trial or setting Baumruk free. A judge will have to decide where the trial will be held.
