University of Florida law school graduate Jason Bohn was sentenced to life in prison without parole for the torture death of his girlfriend, Danielle Thomas, 27, of Danville, Kentucky.
Bohn was convicted of first-degree murder in March in New York City.
The trial evidence included a cellphone recording in which Thomas, a Weight Watchers financial analyst, begged for her life.
Authorities said they thought she accidentally dialed a friend's number as she was being beaten and strangled in June 2012.
Her body was found in a residence, in a bathtub surrounded by ice.
