In the 1990s, Mark Orrin Barton was aiming for the stars. He was a day trader, working in a prestigious office in Atlanta. He had a wife, kids, and a seemingly successful life. Then, in 1999, he shot it all to hell. Quite literally. You may have never heard of Mark or the Day Trading Massacre, but in part one of this two-part series, we’ll examine the man who took the lives of at least thirteen people in a violent, completely unexpected shooting… and who may have taken the lives of two more years before the 1999 massacre ever happened. This is a look at over a decade of unraveling, which ended in a violent workplace shooting that changed Atlanta forever.
