Murder In America

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.

When Linda Wallace stepped into her home, she was horrified. Her drawers were ransacked. Furniture destroyed. Anything of value, stolen. But she didn’t care about that. All she wanted was to find what mattered: Her 9-year-old daughter, Autumn. When she finally did find her, all she could do was scream. Autumn lay on the bathroom floor. The investigation into who killed Autumn Wallace led to an unlikely suspect -- and an even unlikelier conviction.

In 2008, Gregory Green promised the parole board that he was a changed man. When he had murdered his first wife in 1991, he was a monster. Now, he was different. He was ready for another chance. Believing him, the parole board granted him his freedom, and for years it seemed the right choice. He got married. Raised kids. Got a job. Until, in 2016, he betrayed everyone’s faith in him. Police stepped into his second wife’s home to discover the unthinkable: The annihilation of another family.

Marvin Morales took an oath to serve and protect. The Sacramento Sheriff’s Deputy was a shining example of his department… until he wasn’t. A drug scandal. A hidden addiction. PTSD. A series of horrible decisions culminating in the end of his career, and a violent death that no one saw coming.

Christopher Porco was in trouble. At 21, he was drowning in debt, caught in a web of lies, and flunking out of his college fraternity. His loving parents, Peter and Joan, offered to help him figure things out. But instead, Chris did the unthinkable. In the dead of the night, he grabbed an axe, walked into his parents’ bedroom, and committed a crime so heinous that the detectives on the scene could hardly stomach it.
