Pro-wrestler Chris Benoit.
#8. A Wrestler's Rage
In June, World Wrestling Entertainment star Chris Benoit apparently dosed his wife and 7-year-old son with a sedative before strangling them in their Georgia home and then hanging himself using the cord from a weight machine. The popular wrestler left no suicide note. Amid media speculation that the double murder-suicide was brought on by steroid use and so-called "roid rage," a toxicologist concluded that despite finding elevated levels of testosterone — possibly as a result of treatment for past steroid abuse — in Benoit's body, there was nothing in his system that contributed to the violent behavior.
