On July 29, 1999, ashooting spree occurred at twoAtlanta-areaday trading firms, Momentum Securities and the All-Tech Investment Group. Nine people were killed, and 13 other people were injured. The gunman, identified as 44-year-old former day trader Mark Orrin Barton, later committed suicide before he could be apprehended by police.[1]

Police searching Barton's home in nearbyStockbridge 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.[1] 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.[2] Barton was believed to be motivated by large financial losses incurred during the previous two months.[1]

It is the deadliest mass shooting inGeorgia's history.

Events

[edit]

On July 27, 1999, Mark Orrin Barton woke up early in the morning at his home inStockbridge, Georgia, and bludgeoned his second wife, Leigh Ann Vandiver, to death as she slept. The next night, he also beat his children from his first marriage, Matthew and Mychelle, to death. He covered them with blankets and left notes on their bodies, reading in part:[2]

I killed Leigh Ann because she was one of the main reasons for my demise. ... I know thatJehovah will take care of all of them in the next life. I'm sure the details don't matter. There is no excuse, no good reason I am sure no one will understand. If they could I wouldn't want them to. I just write these things to say why. Please know that I love Leigh Ann, Matthew and Mychelle with all my heart. If Jehovah's willing I would like to see them all again in the resurrection to have a second chance. I don't plan to live very much longer, just long enough to kill as many of the people that greedily sought my destruction.

On July 29, Barton went to the offices of his former employer, Momentum Securities, inAtlanta. Witnesses say that Barton briefly chatted with coworkers and said "I hope this doesn't ruin your trading day!" before suddenly pulling out two pistols and opening fire.[3] He shot and killed four people and attempted to execute Brad Schoemehl, who was shot three times at point-blank range. Barton then walked to the nearby All-Tech Investment Group building, where he lured Brent Doonan and Scott Manspeaker, his former bosses, into a private room with assistant Kathy Camp, telling them "I've got something you're going to want to see." He opened fire, wounding all three, with Doonan being shot five times and Camp being left blind. He then left the private room and murdered an additional five victims.[4] Barton left the scene before police could arrive.[5] He had fired a combined total of 39 shots at the two locations.[6] The police searched his house and found the bodies of his family and the notes that he had left with them, in which Barton vehemently denied responsibility for the deaths of his first wife and mother-in-law.[2]

An intense manhunt ensued. Four hours after the All-Tech Investment Group shooting, Barton accosted and threatened a young girl inKennesaw, apparently attempting to secure a hostage for his escape. The young girl escaped and called police.[7] Responding police officers spotted Barton in his minivan and a chase ensued, culminating at a gas station inAcworth, Georgia.[8] As law enforcement attempted to apprehend him, Barton shot and killed himself.[9]

Perpetrator

[edit]
Barton

Mark Orrin Barton (April 2, 1955 – July 29, 1999) was born inStockbridge, Georgia, to anAir Force family and was raised inSouth Carolina. He attendedClemson University and theUniversity of South Carolina. Back inAtlanta, Barton married Debra Spivey, with whom he had two children.[10]

Barton's family moved toAlabama as his employer required him there. Barton grew paranoid and started distrusting his wife. He lost his employment after his performance plummeted. He was also caught sabotaging data of the company that had fired him and served a short jail term for this retaliatory act. Barton found a new employer in Georgia and a mistress in one of his wife's acquaintances, with whom he had an affair. On September 5, 1993, Spivey and her mother Eloise were killed by bludgeoning. Barton was theprime suspect in the double homicide, but he was not charged due to a lack of evidence.[10] He always denied having had any part in them, including in the note that he left behind with the bodies of Leigh Ann Vandiver and his children in 1999.[2] Despite his denials, authorities still consider Barton a suspect in the 1993 murders.[8]

Barton had received a $294,000 insurance settlement from his first wife's death and used the funds to finance hisday trading career, preferring high-risk Internet-related stocks.[11] He married Vandiver, his former mistress, in 1995. His mental health continued to deteriorate, however, and he began to suffer from both severedepression and paranoiddelusions.[10] In the month prior to his killing spree, Barton had lost $105,000, and Momentum Securities had cancelled his account.[11]
