I just watched the press conference that was held after DM's arrest was announced with DP, DM's original lawyer. Kamille reminded me about it tonight. DP said he couldn't get into the framing aspect and that multiple suspects were being sought. Can you imagine what MS must have thought if he saw and heard DM's lawyer speaking about the case? I'd think it likely that MS would assume DM had been talking to his lawyer and maybe even to the police, or that police knew about others involved and that could have caused MS to become paranoid and think DM was going to blab about MS and set him up as the fall guy.
I think that both DM and MS were only interested in saving their own hide and both were prepared to deny any involvement in TB's murder and to place all the blame on the other at all costs to avoid prison, but IMO both were in on everything involved with the crime together all along until they each got arrested. That's when the bond between them began to break, IMO. The only reason either of them had to try and frame the other is because they didn't really trust each other enough to stay silent for long, so both tried to spin a credible story to save themselves and to take the other one down. Neither of them was prepared to sacrifice their own freedom for the sake of the other and everything they did after their arrest was all about self- preservation. Now it may be hard for the jury to know which one to believe and that just may result in a conviction for 1st degree murder for them both.
All MOO.
