A 49-year-old father in Wausau is charged with reckless homicide in the death of his son.  Prosecutors say Robert Glazner failed to manage his 15-year-old son’s diabetes and that led to the teenager’s death.  Glazner made a Marathon County court appearance Wednesday afternoon.  Investigators say Bryden Glazner was vomiting the night before he died last August and his father didn’t make sure his son was checking his insulin levels.  Bryden Glazner had been diagnosed with Type One diabetes in 2014.  Investigators say Robert Glazner resisted being educated about how to treat his son’s disease.
