A man shot his teenage girlfriend during an argument.

21-year-old Dimitri Harrell of St. Paul, Minnesota, was arrested for the shooting death of his girlfriend.

Harrell shot 19-year-old Samirria White, while she was holding their 3-month-old baby, police said.

Harrell told police that he accidentally fired the gun while the couple was arguing. The gun had been stored under the mattress of the baby�s crib.

White was shot in the head at close range, the coroner's office said.

There were several people inside the apartment when Harrell and White began arguing around 3:40 a.m., authorities said.

The woman�s 16-year-old brother heard the two screaming in their bedroom, and he listened as his sister shouted �Don't point that gun at me,� according to the police. Then the teenager heard a gunshot.

He ran into the room and told Harrell to get away from his sister. Harrell told the 16-year-old boy that he had no intention of firing the gun, which he bought a few days before the incident.

White died from her injuries. Her 3-month-old baby was not hurt.

Harrell has two children with another woman. In 2014, the mother of his other children filed for a protective order after Harrell allegedly shoved her into a car while she was pregnant.
