Again I condense a long Pat Brown video into five points:
1) There's no physical evidence of an intruder: no fingerprints, no footprints, no witnesses to a prowler, no obvious sign of entry.
2) Kate and Gerry changed their story. Gerry said he came through the front door with a key. He said everything was locked. Later on the couple said the windows were open.
3) The cadaver dogs evidence. There was a hit behind the sofa, on Cuddle Cat and on the hire car. Pat suggests the body was moved from an insecure place via the rental car to a more remote location.
4) The behaviour of the McCanns following the event. Non-cooperation with Portuguese police, exercising, Kate able to sleep after five days, visiting the Pope, leaving their two children behind.
5) The McCanns rejection of the Smith sighting. Pat says you would leave no stone unturned to discover what happened to your daughter. She suggests the McCanns went with the Jane Tanner sighting because it gave Gerry an alibi, but the Smith sighting did not.
