Parents say students' hotel room doors were duct-taped shut May 20, 2008 FROM THE ASSOCIATED PRESS MILLBURY, Ohio -- Ohio parents are complaining to a school board that a chaperone sealed students in their hotel rooms with duct tape during a high school choir field trip to Chicago. At a heated meeting Monday, Michelle Mata told the Lake Local school board in Millbury that the tactic panicked her son during a recent weekend trip. Sylvia Keeler says she may file charges. Her son, Mark Hummel, says he worried he could be trapped in his room during a fire. School board president Timothy Krugh told parents the tape was meant to keep students safe. Schools Superintendent Jim Witt says the idea was to show if students violated curfew. He says the tape wouldn't have kept them from getting out in an emergency. Copyright 2008 Associated Press.
