There is an Australian series revolving around a Police missing persons unit in Sydney.
Every morning they met and went through the cases.
This was uniformed police, not detectives. The series covers many cases, and really is a must-see for sleuthers, to appreciate the sheer scope of what they do.
Amongst other stories, a 13 year old girl who had vanished. They looked and looked and they found her, returned her home, only to have her be reported again two weeks later. Her mum was a bit rough around the edges but seriously beside herself with worry and grief, even though she suspected the little madam was alive and well just out being a brat...which she was.
There was a man who had gone missing years ago, they were reinvestigating. There was a massive amount of blood found at his house so they assumed he was murdered there and dumped somewhere.
The sheer grind of the questioning, was something else. Literally going into pubs, speaking to people who clearly didn't want to speak to them, chasing hobos and street people for information on a guy who they thought died years ago, and only his family missed.
Of course in the middle of all of this hard slog, an "amber alert" type disappearance can land in their lap which means they literally have to drop the current cases and divert all attention to the new one.
Truly an eye opener. I have found a few episodes on youtube so every one can appreciate the hard work LE do.
This show is produced with Australian values, which essentially means its much more documentary style than your usual cop reality show. It focuses on the grind not the glamour and gives an excellent portrayal of what the Missper team does.
Those of you who have read my posts through this thread remember me pointing out the similarities/dissimilarities to a very famous case here in Aus, Daniel Morcombe, who vanished in literally two minutes, from a bus stop on a busy public highway.
There are eerie similarities, but in Daniel's case, there were witnesses.
Here's a link that covers some of that search. The show is 4 years old now. Daniel's remains have only just been found, and a man is in custody awaiting trial.
Warning - Daniel's family will tear your heart out. They have aged so much, his father has gone snow white.
