Joe and Sheena on Dr. Phil: Murder or Suicide?

I watched this story on Dr. Phil, and I do not see any evidnece to support suicide.  I also do not believe Joe is telling us the truth.  He is slippery and doesn't answer questions.  Then he denies anything when put in the hot seat.

I feel for Sheena's family.  I hope the truth comes out.

Today on Dr. Phil, Joe will take a lie detector test. He should fail it, if you ask me. Will he?
