JEFFERSON, Ohio (WKBN) – A Dorset Township man pleaded guilty Wednesday to killing his girlfriend and was immediately sentenced.

According to Ashtabula County Sheriff William Niemi, Thomas Graley, 38, pleaded guilty to aggravated murder in the death of his girlfriend and mother of his children, 34-year-old Nicole Booth. He was sentenced to 25 years to life in prison.
