EMERSON, Neb. (AP) – A 55-year-old northeast Nebraska man has been charged with two counts of vehicular homicide. Authorities say Robert Mahler, of Hubbard, was driving drunk the night of Sept. 9, on the wrong side of Nebraska Highway 35 near Emerson, when his car struck a motorcycle. Two people on the motorcycle were killed: 20-year-old Christopher Oberg, of Mapleton, Iowa; and his passenger, 19-year-old Alexis Calfee, of Bennet, Neb. They were students at Wayne State College. Authorities say Mahler’s blood alcohol level that night was more than twice the legal limit.
