Kathy Augustine was a rising star in the Nevada Republican party, known for both her ambition and controversial tactics, when she mysteriously died in 2006.
Correspondent Troy Roberts reports on the investigation into Augustine's sudden death.
In the days after Kathy's death, her husband Chaz Higgs says he was so despondent, he locked himself in the bedroom of their Las Vegas home and slashed his wrists. "I actually did it over and over, because I wanted to make sure," he tells 48 Hours. "I laid down and said, 'Good, now I can be with my wife.' And that was the last thing I remember."
