Michael Hill, 54, was sentenced on Friday to life without the possibility of parole for the first-degree murder of Keonna Graham, 24, in 2020.

The 24-year-old had suffered a single gunshot wound to the back of the head.
An autopsy later revealed that she was sleeping on the hotel room bed when the fatal shot was fired.
