Man shot by girlfriend in Hickory Hill after fight has died

MEMPHIS, Tenn. -- Memphis Police say a woman shot her boyfriend at a home in the 4100 block of Sassafras River Drive, near Raines and Riverdale, around 10 p.m. Monday night.

The 48-year-old man died Tuesday afternoon.

Investigators say the couple got into an argument after the victim punched his girlfriend's son in the face.

The 19-year-old reportedly took his mother's car without permission.

The woman told police she only opened fire after her boyfriend shot at her son.

Officers found several spent casings, but not another weapon.

The woman was taken into custody, but it's unclear if charges will be filed against the shooter.

This is the 31 homicide so far this year.
