KANSAS CITY, Kan. (AP) — A 55-year-old Kansas man has admitted that he killed his girlfriend during a fight aboard a cruise ship off the coast of Florida last year. Federal prosecutors announced Thursday that Eric Duane Newman, of Topeka, pleaded guilty in federal court to second-degree murder. Prosecutors say Newman and 50-year-old Tamara Tucker were on a cruise ship heading to the Bahamas in January 2018 when they began fighting inside their cabin. Newman admitted strangling Tucker and pushing her over the cabin room balcony railing. She fell from the 13th deck to the 11th deck. Tucker, of Lawson, Missouri, died from blunt force trauma from the fall.
