Spammer and family dead in apparent murder-suicide: Edward Davidson, 35, is the poster child for why spammers need to be prosecuted. In April 2008, Davidson pleaded guilty to tax evasion and falsifying e-mail headers on messages advertising penny stocks. He was sentenced to 21 months in a minimum security US prison camp in Colorado. A few days after his July 2008 escape from prison, Davidson was found shot dead in an SUV along with his wife and 3-year-old daughter. Spared were his 7-month-old son and a teenage daughter, who survived a gunshot wound to the neck.
