Lynn was walking with a group of friends back to the Spelman campus when they passed by the fight.
"One of the friends actually heard the gunshots, actually saw the weapon and told her to get on the ground," said Lt. Keith Meadows of the Atlanta Police Department. "Before she was able to get on the ground she was struck in the chest by a stray round."
Bystanders rushed to help Lynn.
"I walked up to the girl 'cause she was laying on the ground," said witness Danays Marquez. "She was drenched in blood and it looked like she was taking her last breath."
A bullet also hit an 18-year-old Clark-Atlanta student in the wrist. He was taken to Grady Memorial Hospital.
Two people were arrested at the scene, but police did not reveal the charges against them.
