Police released video Thursday evening of three men wanted in connection with the attack. They are seen in the footage getting into a dark-colored Nissan Armada SUV.



Calub's family flew in from California after the attack and in a statement provided only to Channel 2 Action News, the family said:



"Mark was visiting a friend in Atlanta for the first time, and out of nowhere he and his friends were attacked as they walked down the street. What was supposed to be an enjoyable and memorable trip turned into a nightmare, and Mark is now in critical condition far away from home. Mark is a well-loved brother, son and friend to so many, and we are beyond devastated by this tragedy. Please help us spread the news so that those responsible are brought to justice so they can't hurt others like Mark again. We're so heartbroken that anyone would do this to him. He is always full of life and an awesome person to be around. If anyone knows anything about this attack, please contact the Atlanta Police Department. It would also mean a lot to us as well if you would please respect my family's privacy in the meantime as we go through this difficult time."
