7. Michelle Paet
Michelle Paet was living in Las Vegas with her husband, Nathan, a staff sergeant with the US Air Force and their four children. On the night of December 1st, 2010, Nathan left to work a nightshift at the air base, but was shot 5 times in the back before he could get into his car. He stumbled back inside, but eventually died from his wounds. The murderer turned out to be Michelle’s lover of only six months, Michael Rodriguez, who had conspired with Michelle to kill Nathan. She knew she’d receive $400,000 from the military in the event of Nathan’s death, plus $250,000 from a life insurance policy. Michelle and Michael both received life sentences.
