There is a dispute as to whether May 2nd or May 3rd is the time something happened to Maddie.
If Maddie died...maybe something happened on the 2nd but she didn't die immediately...
Maybe she died at some point during the day of May 3rd but her body could not be removed until after dark...
Was it dark in PdL around 9.05 when Gerry left the table (supposedly)
Was it dark at 9.30 when ROB left the table?
Is this why the PJ are focusing on that night regardless of so many details indicating May 2?
Diane Webster not immediately leaving the table is the most 'telling ' point to me.
I cannot believe any one of the tapas 7 remaining at the table and not joining in the turmoil the very second it was 'discovered' unless there was another 'reason'.
