The following is the text of an e-mail sent to The Associated Press by Chris Zinkhan, brother of University of Georgia professor George Zinkhan:
"I and certain other members of my family have been in contact with detectives of the Athens-Clarke County Police Department since learning of this tragic event on Saturday. In fact, I contacted them to offer my assistance. Subsequently, we have communicated with the FBI. We are doing all we can to prevent any additional violence.
"Our thoughts and prayers are with the victims, their families, and their friends."
