VIDEO: A city is in disbelief after a Wausau firefighter/paramedic is charged with sexual assault while on the job. 33-year-old Clifford Heiser is accused of inappropriately touching a female patient in the back of an ambulance earlier this month. Fire, police and city leaders held a press conference Tuesday afternoon to discuss the allegations. "We as a department are very humbled today, there's no department or organization that believes that this type of accusation would ever be brought against one of their members," said Wausau Fire Chief Tracy Kujawa.
