A Baton Rouge man shot his girlfriend, injuring her, then fatally shot himself following an argument between the two early Friday morning, police said.

Lamarcus Ray, 35, died at his Doral Drive home just off Coursey Boulevard from what police described as a self-inflicted gunshot wound. Ray’s girlfriend, a 31-year-old woman, was taken to a hospital with non life-threatening injuries after being shot in the leg, said Cpl. L’Jean McKneely, a Baton Rouge police spokesman.

The shooting remains under investigation.
