It was widely known from the start that Madeleine was wearing pyjamas when she went missing.
The pictures released of identical pyjamas were at odds with those allegedly seen worn by the child the Smiths saw.
MS had been home for 2 weeks before he received the suggestive phone call from his son, ie at least 6 days after the release of the pyjama photo but at least 2 days after RM had been declared arguido.
Was the real trigger the picture of the man in the media or the pyjamas which didn't match the ones they saw?
IMO, it could have been a slow realisation, perhaps even in the reverse order of the emerging news.
- A named local man had been made arguido.
- You vaguely remember crossing paths with a man carrying a child.
- Try to think back to your recollection.
- Off to check for any other details. The pyjamas, not identical to your recollection, but still similar.
- Think about it a bit more.
- It's still bugging you. Check with other family members.
- Decide to report the incident, just in case.
