April 2, 1955 - Mark O. Barton

On July 29, 1999, a shooting spree occurred at two Atlanta-area day trading firms, Momentum Securities and the All-Tech Investment Group. Nine people were killed, and 13 other people were injured.

Police searching Barton's home in nearby Stockbridge found the bodies of his second wife and the two children from his first marriage, murdered by hammer blows inflicted before the shooting spree started. According to a note left at the scene by Barton, his wife was killed on July 27 before the children were on the following day. Barton was believed to be motivated by large financial losses incurred during the previous two months.

It is the deadliest mass shooting in Georgia's history.
