Olivia Cox, 22, and Megan Smith, 23, killed, and William Maddox, 23, critically injured in car wreck on Athens Loop in Athens, Georgia

 A black Nissan Sentra with five people was traveling on the inner loop when the driver lost control and over-corrected, causing the car to travel across the median and into the outer loop, where it hit a black Cadillac, according to McIlvaine. The two women who died and injured man, all from Snellville, were in the Nissan. 

Cox's family did not want to make a public statement until they have an opportunity to talk with the families of the others involved, but said they believe the accident was weather-related.

Saturday's memorial is scheduled for 7 p.m. at the South Gwinnett baseball field. Cox was a softball player and bat girl for the school's baseball team and both young women loved the outdoors, friends and family members said.
