What were you hoping to prove?
It is a public forum. I'm just providing information, I'm afraid people have to form their own opinions and inferences from that information.
A further interview I found interesting:

On the following day May 3rd they met at the South West bar in Lagos marina at about 11.30. He does not remember whether Robert or Michaela phoned him to ask for the meeting or if they had agreed upon it the day before. The witness and J**** went to the place on foot.
When they arrived Michaela and Robert were already there. They talked there for half an hour, but as it was very noisy, Robert suggested they went elsewhere. The four of them left in the VW transporter to Palmares Golf, about 5 minutes away by car, a place where the witness and his son had never been.
They remained there conversing for about 3 hours, very much at the insistence of Robert. In spite of the witness and his son being hungry, Robert prolonged the conversation, saying that he was not hungry. Only at about 16.00 did Robert and Michaela drop the witness and his son near to their shop. On that day they had no further contact, neither personally or by phone.
