The witness statements will prove it. Matt was accused of being involved on 10 May 2007 by the PJ and he started providing interesting info especially as he wore a watch that night. He said Kate left at 21:50 to check and nobody apart from Gerry said she was gone long. 21:50 corroborates with the waiter that served Russell his steak moments before Kate left the table. That puts the alarm before 22:00 and the Smith sighting.
Russell managed to eat most of his dinner before the alarm.
They then all went back to 5a, the friends all say they all headed back to 5a. So how much time would have gone by, by the time they had all gone back to 5a to search? Gerry tried the blind, Dianne said she tried too so she must have known that Gerry had lifted it up, so how much time had gone by then?
A waiter saw Gerry searching around the pool area, when he left the restaurant there was already about 40 people gathered outside to search for Madeleine.
So did Gerry leave the apartment with Madeleine when the people were gathering?
