BATON ROUGE - A man was arrested Wednesday after a woman he allegedly shot Saturday died in the hospital. 

According to the Baton Rouge Police Department, 31-year-old Gerald Smith drove 41-year-old Cathy Watson to a hospital Saturday night with a gunshot wound. Officers reported that Smith said Watson accidentally shot herself. 

After she passed away in the hospital, the coroner determined Watson's injuries were consistent with a homicide. 

Officers later learned Smith and Watson got into a physical fight at a laundromat on Greenwell Street earlier in the night Saturday. 

Smith was arrested for second-degree murder, illegal use of a weapon and domestic abuse.
