Teen sentenced 8 to 16 years in Walgreens parking lot stabbing

HUNTING PARK (WPVI) -- A teenager has been sentenced 8 to 16 years in prison for the murder of another teen last summer in the Hunting Park section of Philadelphia.

18-year-old Keyarra Frisby admitted to stabbing 17-year-old Anita Cotton to death in the parking lot of a Walgreens drugstore in the 4200 block of North Broad Street around 3:45 a.m. on July 5, 2015.

Police say two groups of girls got into a fight after watching Fourth of July fireworks at Penn's Landing.

A pedestrian found Cotton lying in the pharmacy parking lot and quickly flagged down a patrol car.

Cotton had suffered a stab wound to the neck. Officers rushed her to Einstein Medical Center where she was pronounced dead.

Cotton left behind a young daughter.
