Nicholas Schwieterman of Chickasaw, left, listens during a Monday appearance in Celina Municipal Court with his attorney, Scott M. Calaway of Dayton. The 22-year-old faces four counts of aggravated vehicular homicide and two counts of operating a vehicle while intoxicated. The case, which stems from a Saturday morning crash that claimed the lives of four area men, is scheduled to go before a Mercer County grand jury later this week.
