55-year-old Eric Duane Newman, of Topeka, Kansas, pleaded guilty to one count of murder in the second degree for killing Tamara Tucker with malice aforethought.
According to the admissions made in connection with the plea, Newman and Tucker boarded the Carnival cruise ship Elation on January 18, 2018, in Jacksonville, Florida, to take a round-trip voyage to the Commonwealth of the Bahamas.
The couple was staying together in a cabin room on the 13th deck of the cruise ship.
Before midnight on Jan. 18, Newman became involved in a verbal argument with Tucker inside their cabin room.
At approximately 12:15 a.m. on Jan. 19, Newman physically attacked Tucker, and strangled her by placing both of his hands around her neck.
In the process of strangling her, Newman pushed Tucker over the cabin room balcony railing causing her to fall to her death onto the 11th deck. Ms. Tucker died from blunt force trauma as a result of the fall.
At the time, the cruise ship was sailing on the high seas in international water, approximately 30 nautical miles from New Smyrna Beach, Florida.
