From
The French Paper:
Meanwhile
Le Parisien quotes a friend of Thomas [the Dupont de Ligonnèss eldest child], with whom the 18-year-old spent the day of 5 April.
He was smiling and joking as usual, there was nothing unusual in his behaviour, says the friend.
Then around 7pm he got a phone call that changed things, says the teenager, whose real name is not given.
It was from Thomas father saying that his mother had been in a bike accident and was in hospital.
Her life was not in danger, his father said, but he insisted that Thomas come home that night.
After Thomas had gone home, his friend sent him a text asking him if everything was ok.
He replied:Im ill, Im not coming back.
According to the teenager quoted in the newspaper neither that message not subsequent ones sounded like his friend. They were too short, with no humour. Thomas wrote long texts the impersonal tone of these was not him at all.
