If Jodi's family were searching with Luke, it's strange that they have absolutely nothing to do with him.
The police are not looking for anyone else.
Yes, you are correct I have no evidence the family were strange but I knew someone who lived in the vicinity of the crime and they said the family were definitely strange. They lived in the area.
Why was Luke's mother's business targeted if the family are popular?
I'm going to have to disagree with you, Luke is guilty. It's also very telling that some members of his own family have no contact with him.
You also never replied about Luke seeing someone else while seeing Jodi, which he was.
When Jodi did not turn up to their arranged meeting, why was Luke not asking where she was?
He didn't ask because he knew.
