Teacher charged in ear bite attack ST. PAUL, Minn. (AP) A middle school teacher is accused of biting off part of a mans ear during a confrontation at a St. Paul diner. Prosecutors say 30-year-old Susan Mukuhi Mwarabu was drunk when she attacked the man at the Uptowner about 4 a.m. Sunday. A criminal complaint says the 33-year-old man was eating with friends when one made a comment about one of the women with Mwarabu. It says she approached the group of men, licked the victims ear, then bit off part of it. Mwarabu teaches sixth grade at Northfield Middle School. Superintendent L. Chris Richardson tells the St. Paul Pioneer Press that school officials will have to learn more about the case before making a decision on appropriate action.
