CCTV footage of seven persons of interest in the murder investigation of retired police captain David Dorn has been released.
One suspect is filmed pointing a handgun at the door as others duck under the shutter and run around the store at the time when Dorn was fatally shot.
Capt. David Dorn, 77, was shot and killed outside Lee's Pawn & Jewelry in St. Louis at around 2.30 am on Tuesday.
Dorn's body was found on the sidewalk in front of the shop that belonged to his friend as people did their best to save him.
Police believe he was trying to protect the shop from the looters and reports indicate that his killer stood over him as he died without contacting emergency services.
St. Louis Police Department has now released private CCTV footage from inside the shop that showed seven men enter through the front door at the time of the shooting.
One appears to have an injury to his left hand and another is seen holding what looks like a gun.
St Louis police are offering $45,000 for information leading to an arrest, a sum that is now growing thanks to public donations.
In the video the store appears to already have been looted and wrecked, with windows shattered, display cabinets emptied and trash discarded on the floor.
But a police source told the Associated Press that looters, who had broken into the shop during unrest that followed a peaceful protest over the death of George Floyd, were responsible.
In a disturbing twist, Dorn's death was reportedly streamed on Facebook Live.
“I just seen a man die on live man! Smh,” state Rep. Rasheen Aldridge posted on Facebook.
Another member of the public also claimed on Facebook that looters stood over Dorn and filmed as he died, rather than call for assistance.

The retired captain had served 38 years on the St. Louis police force before retiring in October 2007. He then became chief of Moline Acres, a small town north of St. Louis.
The Ethical Society of Police, which represents black officers in St. Louis, said in a news release that Dorn was "the type of brother that would've given his life to save them if he had to".
On Tuesday, Donald Trump tweeted that Dorn had been "killed by despicable looters."
Capt. Dorn's death came on a violent night in , which saw four officers shot, officers pelted with rocks, and businesses burned and robbed.
