Nadisha Beckford had claimed that she was acting in self-defence when she stabbed Lakeisha Mackey during a fight in the parking lot of the Mayfair Hotel on February 20, 2021.
Ms Mackey died in the hospital two days later.
The self-defense claim was rejected by a jury that unanimously convicted Beckford of murder earlier this year.
Beckford's lawyer, Dorsey McPhee has indicated she will appeal both the conviction and sentence.
