Memphis police say a teen who stepped out of a car to help a stranded motorist at an intersection was shot to death by assailants who opened fire, wounding three others.

The 17-year-old was waved down by a woman whose car had broken down Thursday night around 7:30 p.m.

Memphis police say in a news release that two suspects exited another vehicle, approached on foot and began firing at the teen and another 15-year-old.

The teens were shot and the stranded motorist, along with an 18-year-old woman who was with the teens, were hit by bullet fragments. Police say the three suffered non-life threatening injuries.

The suspects fled on foot and Memphis police are continuing to investigate.

The teen, who wasn't identified, was pronounced dead at the scene.
