The man’s mother, Tina Robbins, told Channel 2, “I think that someone had his attention and someone else came behind him and he took a horrific blow to the back of the head.”
Gamble, who underwent brain surgery at Wellstar Kennestone, has been unable to tell police what happened. Robbins said her son’s condition is grave, and a recent MRI showed that he may have had a third stroke on Monday.
His family has set up a Facebook page, “Justice for Zach Gamble,” seeking information about the incident. Robbins said that she hopes someone at the party will speak up.
Pierce said, “His mother have been doing a tremendous job keeping this at the forefront of the public, so hopefully some tip will come about to break this case.”
Police asked anyone with information about the incident -- and specifically, what happened from 5 a.m. until 6 a.m. March 25, when police received the 911 call from the cab driver -- to call the Cobb County police's Crimes Against Persons unit at 770-499-3945.
