New dash-cam video was released by the Seneca Police Department in South Carolina that shows an officer shooting an unarmed teen in a drug-sting operation. Lt. Mark Tiller fatally shot 19-year-old Zachary Hammond on July 26 in the parking lot of a Hardee's.

A lawsuit filed by Hammond's family said the teen was on a first date with a woman when he stopped for a burger at Hardee's. The police said the woman was part of a drug-sting operation arranged by police. When the officer drove up behind and approached the silver sedan Hammond was driving, the teen attempted to drive away. That is when Lt. Tiller shot Hammond.

Tiller said he believed Hammond would run him over with the car. No charges will be filed against the officer by the state of South Carolina. The state said Lt. Tiller acted in self-defense. The US Justice Department is now investigating the incident.
