Quayle’s family members are confused about why their loved one was killed on her way to work.
“Now we have all these unanswered questions about why and who did it and all these things,” Martin said. “We haven't had much information.”
Police told WSBTV that investigators recovered surveillance video from a QuikTrip gas station near the scene of the crash on Upper Riverdale Road. Cameras captured the moment Quayle's Mazda swerved into oncoming traffic.
Authorities believe the video is the key to figuring out who is responsible for shooting Quayle.
Investigators said they want to speak to the driver of a white SUV and the driver of a gray car.
Quayle was an aspiring model who had recently moved to the area from Los Angeles.
Police said they believe the fatal shooting was random.
"It seems to us to be random at this time,” Clayton County police Capt. Scott Stubbs said. “We have not been advised in reference to anybody shooting in the area.”
Relatives said they cannot imagine that anyone would want Quayle dead.
“She was positive about any situation, even though she's going through a whole lot, she made the best of everything,” Martin said. “I mean, everybody loved her."
Quayle's family made the decision to remove her from life support Wednesday.
Quayle's family said she was new to town, did not know many people and surely did not have any enemies.
