Chris Benoit & Nancy Benoit: Behind a Troubled Marriage

In the days before pro wrestler Chris Benoit killed his wife and child and hanged himself, the couple argued over whether he should stay home more to take care of their mentally retarded 7-year-old son, an attorney for the wrestling league said Wednesday.

"I think it's fair to say that the subject of caring for that child was part of what made their relationship complicated and difficult, and it's something they were both constantly struggling with," said Jerry McDevitt, an attorney for WWE. "We do know it was a source of stress and consternation."

McDevitt said the wrestling organization learned from the couple's friends and relatives that the Chris and Nancy Benoit were struggling with where to send the boy to school because he had recently finished kindergarten.

He also said Benoit's wife didn't want him to quit wrestling, but she "wanted him to be at home more to care for the kid. She'd say she can't take care of him by herself when he was on the road."

Meanwhile, on The Today Show, Meredith Vieira confronted Vince McMahon.

She asked the WWE owner how his company could vehemently deny steroids were involved in the murders before toxicology results were revealed. But McMahon said a press release sent out earlier this week was "reacting to the hysteria of the media," telling the press to quit speculation that "roid rage" was a factor in the killings - until evidence proved otherwise.
