An Ohio man who bludgeoned his girlfriend to death with a hammer before dismembering her and scattering her body parts around the apartment complex where they lived has been sentenced to 15 years to life in prison.

Robert Knight was sentenced Wednesday in Franklin County Common Pleas Court. The 51-year-old Columbus resident pleaded guilty to murder last month and will be eligible for parole after 15 years.

Investigators say Knight killed 44-year-old Tracey Moore in June after an argument. Police and maintenance workers found her head and arms in his freezer and other remains in his backed-up toilet and throughout the apartment complex and its grounds.

Knight says he's "very apologetic to Tracey."

Moore's brother, Carl Laury, says Knight should have no chance for parole.
