If you think the Gaspar statement is unusual, then have a read of Yvonne Martin's statement.
She was a UK child protection officer (on holiday nearby at the time), and went to see if she could aid the McCanns after she heard the headlines on the TV the morning after she disappeared. She got there about 10am that morning, and spoke to Kate.
Other than saying that Kate was questioning 'why would a
couple steal her child' and that they were checking on the kids every hour (not every half hour as per their later statements) the interesting stuff is what she mentions about another of the McCanns group. She didn't know who he was, but was convinced she met him previously, and as time went on believed it was through her line of work as either a witness or as a suspect.
The person turned out to be David Payne, and she was that concerned about him she wrote anonymously to UK Police, basically with a view to get them to check if he was known to them or on any sex offender registers.
This later led (along with the Gaspar statement) to numerous conspiracy theories that the McCanns & Co were themselves part of a pedo ring.

Also seem to remember though, after her name became known some of the British press did a few hit-pieces on her, so unsure of how reliable you could consider her statement & opinion to be.
