A 23-year-old man's attempt to show his girlfriend a pistol ended in tragedy when the gun discharged, killing her, Jefferson Parish Sheriff's deputies said.

Deputies said 23-year-old Averyell Davis was shot in the abdomen Monday night.

Sheriff's spokesman Col. John Fortunato said Curtis C. Murray has been arrested and booked with one count of negligent homicide.

The couple was in the living room of their home in Gretna when the gun discharged, Fortunato said.

He says Davis told first responders that her boyfriend accidentally shot her, Fortunato said.

Davis died shortly after arriving at the hospital.
