Dashcam video has emerged showing a black South Carolina man running from his car after a traffic stop by a white officer, who gave chase before shooting him dead.
The footage, released by the South Carolina Law Enforcement Division, does not show Officer Michael Slager shooting Walter Scott but does reveal more about the minutes before the killing in North Charleston last Saturday.
Slager, who has been charged with murder and dismissed from the police, is seen approaching a car and asking the driver for his licence and proof of insurance.
The patrolman tells Mr Scott he has been pulled over because of a broken brake light. After a brief exchange, the officer returns to his patrol car.
The 50-year-old gets out of the vehicle, and Slager tells him to stay in the car. Several seconds later he leaves the black Mercedes-Benz again and runs away.
After Slager gives chase, someone can be heard shouting: "Taser, taser."
The 33-year-old patrolman said in a call to a dispatcher that he fired his weapon because Mr Scott took his stun gun and he feared for his life.
But he was charged over the killing after a separate video, filmed on a mobile phone by an onlooker, showed the officer firing eight shots at Mr Scott's back as he flees.
In the second video, Mr Scott does not appear to be armed.
A post-mortem examination has found Mr Scott had multiple gunshot wounds on the back of his body.
His father has said his son, a father of four, may have run away because he owed child support money and did not want to go to jail.
Mr Scott owed nearly $7,500 (£5,100) in child support when he was pulled over by Slager, according to court records cited by the Associated Press.
He had been jailed three times for failing to pay child support, reports AP.
He was sentenced to six months in 2008 and then in 2011 spent a night in jail for missed payments, and again a year later.
The dashcam video emerged as a man who was hit with a stun gun by Slager in a 2013 incident said he would sue.
Mario Givens, 34, told a news conference Slager came to his house, pushed in the door and fired the stun gun at his stomach.
Mr Givens, who was unarmed, filed an excessive-force complaint at the time, but Slager was exonerated and allowed to remain on the force.
North Charleston police have said they will now review the case.
