It's hard to say what's most horrifying: How Jeff Wright was killed, who killed him, or why she says she did it. The woman accused of committing murder is Jeff's wife, Susan, 27, a stay-at-home mother of two. "I did not want to die," says Susan, who now faces life in prison. "This was a brutal, terrifying, sadistic relationship that spanned years," says Susan's attorney, Neil Davis. Susan Wright stabbed her husband 193 times. And Davis says he believes that Susan's husband, Jeff Wright, triggered the attack that ended his life: "I hate to say it, but some people just deserve killing." That's how a lot of Texas lawyers interpret self defense. But what makes this case different is that Susan and her lawyers are saying it on the record. "She had to kill or be killed," says Davis.
