ATLANTA - Police in Clayton County released surveillance video from MARTA bus on Thursday calling it the biggest break in the investigation into a model gunned down while driving down the road.
The video from the bus shows what police are calling a “person of interest” in the case of Kelsey Quayle’s murder. The 28-year-old model was shot while driving to work along Upper Riverdale Road and Tara Blvd. just before 7 a.m. Oct. 8.
Police said the video shows a man trying to board the bus two minutes before Quayle’s car crashed.
"He gets out of his car and tries to get the bus driver to open the door to the bus, which he does not," said Capt. Scott Stubbs, Clayton County Police Department.
Police said, for some reason, the man then follows the bus on Upper Riverdale Road in a car, that's when he comes in contact with Quayle's vehicle when the bus was stopped once again.
"That person gets back into a vehicle, we believe between a 2012 and 2014 Chrysler 200. the vehicle was a light gray or light-colored sedan," said Capt. Stubbs. "He steps out of the vehicle, he steps into the lane of traffic, that's where we believe Ms. Quayle was exiting her vehicle from 75 onto Upper Riverdale Road, making her turn, and apparently she traveled into the lane where he had traveled out into."
Police said Quayle was shot moments later. Authorities do not believe she was targeted.
It's unclear why the man was trying to board a bus, even though he had a vehicle nearby. Police said it is also unknown why he tried to board again. That's why investigators hope someone who sees the video can provide his name and some answers in this case.
"We feel very confident that if someone can come forward with some information about this person of interest, that it can take us down a much more positive direction," the captain said.

Police previously release video from a nearby gas station, but investigators believe the MARTA video may be the best hope as identifying their “person of interest.”
Family members told FOX 5 News Quayle was shot in the neck and the bullet became lodged in her spinal cord at the base of her brain, causing catastrophic brain damage. She was rushed to Grady Memorial Hospital where she was on life-support, but was taken off after doctors determined she was brain dead. She passed away a few days after the shooting.
Family members told FOX 5 News that Quayle moved to Georgia a few months ago with her boyfriend, excited to pursue her modeling career in Atlanta. She got a job at a dentist's office in Riverdale and was driving to work Monday morning when her life took a tragic turn.
