Kelsey Quayle, 28, was shot in the neck while driving in Clayton County, Georgia, on Monday

Police have released video footage recorded moments before a young model was shot in the neck as she was driving to work then crashed head-on into oncoming traffic in Georgia.

Kelsey Quayle, 28, was placed on life support after she was shot while driving on Upper Riverdale Road in Clayton County at 7am on Monday. She was declared brain dead and died two days later on Wednesday.

Officials shared video footage from a nearby QuikTrip gas station recorded seconds before Quayle's Mazda 626 crashed into a Suzuki XL-7 and a Ford Escape, leading the Ford to flip over, according to Clayton County Police.

Cops are pleading for the owners of a white SUV and a gray sedan pictured passing Quayle's vehicle in the gas station surveillance video to come forward to see if they can provide information on the devastating crash.

Police shared the video on Facebook on Friday pleading for the car owners of two mystery vehicles that passed Quayle's car before she was shot and crashed to share what they saw

'Here is video footage captured from various angles just seconds before the crash involving Kelsey Quayle occurred. We are asking anyone who may have been traveling along Upper Riverdale Road, in the area of the crash (approx. 7:02 a.m.) to contact us,' Clayton County Police posted on Friday.

'We would especially like to speak with the driver of the white SUV and the driver of the gray sedan that is seen passing Kelsey's vehicle as it is traveling in the lanes of oncoming traffic,' they added.

It's not clear how the young model was shot and police have not identified any suspects. The investigation has been classified as a homicide, Sgt. Ashanti Marbury announced on Friday, according to AJC.

Quayle had just moved to Atlanta, Georgia from California in August with her boyfriend to pursue a modeling career.

She was driving to her job at a dentist office when the crash took place.

Quayle passed away on Wednesday two days after she was driving to work and was shot in the neck, leading her to drive into oncoming traffic and crash head-on into two vehicles on Monday

Her family have no idea why she would've been targeted - and think she may have been caught in crossfire

Her sister Kayleigh told Fox 5 Atlanta, 'I just want to know who did this. It's ridiculous. She didn't deserve this.

'She was beautiful, she was the sweetest person she was humble she was a model but she never let that get to her head. She loved everybody, everybody loved her.

'Right now a theory would be road rage, or maybe just a crossfire maybe but we just have so many unanswered questions.'

At first Quayle was taken to Grady Hospital where she was declared brain dead. Her family switched off her life support on Wednesday.

Officers responded to the three-car pile-up on Monday thinking it was just a crash. Then they learned she was shot in the neck and now cops believe the shooting caused the crash.

Captain Scott Stubbs, Clayton County PD said: 'Which we believe was the primary cause of her not being conscious, leaving the roadway into the length of traffic.'

Family members tell FOX 5 News the bullet entered Quayle's neck, severing her spinal cord at the base of her brain, causing catastrophic brain damage.

A GoFundMe Page has been set up by Quayle's sister Kaleigh Martin to help with funeral costs and has already raised over $17,000 for her.

A memorial for her will take place on October 20 in Calimesa, California.
