An 89-year-old man apparently died of natural causes while visiting his wife's grave on their 64th wedding anniversary. A report by the medical examiner's office in Milwaukee said Joseph Neumaier's body was found Wednesday near his wife's grave at Holy Cross Cemetery. His wife, Mary, had died about two years ago and he visited her grave every day, according to his son, Fred. Neumaier will be buried beside his wife in the cemetery.
