The family said "it was their understanding Mark had provided information"..The doctor or lawyer could not provide specific info without Mark's permission...The location of Lori's body is the only thing I can think of they can mean..
If Mark knows where the body is, he may try the "She committed suicide and I couldn't bear for the family to know" routine
He loves to fool ya..I don't trust what he says.Could be a game.
I thought about that too. He's such a LIAR.
