A beer deliveryman shot in his head outside an Algiers gas station on Tuesday has died of his wounds, New Orleans police said Friday.

Authorities have not yet released the name of the 19-year-old victim, who was shot outside a Chevron station at the corner of Gen. De Gaulle and Shirley drives by an unknown assailant. Police believe the attacker targeted his victim.

The man’s condition appeared at first to be improving, according to police, but he died on Thursday.

Fourth District Lt. Preston Bax said at a commanders’ briefing on Wednesday that investigators had obtained clear surveillance video of the shooting. The victim was unloading beer from a truck when a hooded attacker approached him from along a wooden fence in the 3300 block of Florence Drive, the officer said.

The perpetrator and his victim, who appeared to know one another, exchanged words for several seconds, standing just feet apart. The suspect then raised a gun he had at his right side and fired, according to police, fighting off the victim’s attempt to wrest it away.

The bullet went into the victim’s head through his neck and left through his left eye, police said.

The attack left a large pool of blood on the ground between an ice chest and a pump at the gas station. Minutes after the attack occurred, a distraught woman who said she was the victim’s mother showed up at the scene.
