four - The Police had already searched that area but they searched it again, so did not search very it well.
five - he failed the lie detector test too so they had two suspects. yet they did not treat him as one.
six - They collected the clothes he had been wearing on the day the girl had gone missing and found her blood.
Why did they not check his cloths when he failed the lie detector test.
IMO Just shows how the incompetence of police can let suspects get away with murder.
The Police didn't investigate the man with the dog further as he had an alibi, he said he was on stage performing when the little girl went missing. They checked this out and found it to be true. It wasn't until they found the mother had made a mistake and the little girl had gone missing much earlier that they then investigated the man. They found the clothes he had been performing in and there were tiny drops of blood on them, which belonged to the little girl.
It was an American programme by the way.
