A hearing will be held next month for the suspect accused of murdering a man in rural Laclede County back in early July. 65 year old Matthew Rumbaugh will be in court on September 4th for a preliminary hearing. Rumbaugh was arrested for allegedly going to Chad Gerber’s home and shooting him and his son in the head. He apparently owned the garage where Gerber worked. Rumbaugh has been charged with first degree murder, assault, and two counts of armed criminal action. 15 year old Riley Gerber died from his injuries July 12th. However, prosecutors have not yet amended the charges to also reflect the teenager’s murder. They say the case is still under review.
