I have no idea if this guy is involved in the murders of his wife and adult daughter or not, but all I have to say is that when someone says something like this:
"Stodden said his concern with taking an additional polygraph examination is that in diverts detectives from focusing on the real suspects. "I'm sure they have absolutely nothing on me, other than the fact that I was closest to Mary," he said."
...I hear it being said in Scott Peterson's voice. He said that ALL THE TIME. "Hate me, I don't care. Focus on finding Laci." And we know that his focusing on finding Laci consisted solely of dating Amber Frey.
