A Georgia College Professor and her brother have passed away after a car accident late Monday night in Milledgeville.

"We truly lost a beautiful angel," Mike Martino said.

Program Coordinator for Exercise Science at Georgia College, Mike Martino, has worked with Everett for 19 years. He says he'll miss seeing her smile every day.

People in Milledgeville are mourning Georgia College exercise science lecturer Allison Everett and her brother David Black.

They died in a car accident late Monday.

Baldwin County Coroner John Gonzales says the 3-car accident took place in the 600 block of Lake Laurel Road.

The Georgia State Patrol says Ken Everett, Allison Everett and David Black were riding in a Nissan Altima when they were struck head-on by an Acura TSX, which forced them into a ditch. A Mazda truck hit the back of the Acura after the collision.

Gonzales says Allison Everett and David Black were pronounced dead on the scene.

Martino says the other victim was Allison's brother, David Black.

"David was a very good artist. He was visiting from California and had come in for the actual funeral services for Allison's mom.

Allison Everett was also a fitness instructor at Bodyplex Fitness. Personal Trainer Jared Wilson says today has been a whirlwind of emotion.

"To see the emotion on peoples' faces the instant they found out about it, showed how much she meant to them on a personal level," Wilson said.

"You never know when it's your last day," Martino said. "And Allison definitely gave unselfishly of herself."

Allison's husband Ken was airlifted to the Medical Center, Navicent Health where he is listed in critical condition.

Besides her husband, Allison Everett leaves behind two daughters and a son, all adults.

Georgia State Patrol is investigating the accident to see why the two cars collided.
