The father is supposed to have an alibii as someone recognised him at the reconstruction. Said he was seen in his car elsewhere and could not have been at the scene of the crime. Apart from that nothing else at the moment.
I think I read that the father of the girl is going to become a regular character for the next 10 months. Don't know why. The latest we know is that he has an alibi, which (at the moment) seems to be genuine.
