I’m not sure if this comment will be well received, but I’ve not seen a PC where family didn’t speak directly to the missing persons or the suspect. Meaning: no one said “please if you’re watching this, please bring her home, please don’t hurt her.” Or “Naomi if you’re watching, we love you, we are going to find you”, etc. which makes me wonder if whatever evidence was found in the car that led police to believe a crime had been committed, was enough evidence to determine there was an attack and that a person could not have survived that attack, and at this point they are looking for the suspect, and they believe she isn’t alive. Forgive me if this is harsh, I don’t mean it to be. But could the family already be made aware that she may not be alive? This is all just IMO.
