It was the last thing I thought of before going to sleep last night and the first thing in my mind this morning.
The five year old boy missing in Middlesborough.
They found him - eleven hours after he went missing. What his family must have been through in those eleven hours doesn't bear thinking about.
It is amazing the distances small children can travel and how quickly they can vanish.
I was reminded of a day at the beach when my two oldest children were aged 2 and 4. It was quite a busy day, lots of people about, but we found a quiet spot in front of the long row of beach huts.
I noticed a man leaning on the sea wall watching us. He made me feel uneasy. There was something about him at odds with the other people at the beach. I tried to tell myself he was just someone out for a walk, but he stood there watching my kids for far too long.
You just know when someone doesn't fit in don't you? When they don't feel right.
In the end I decided to pack up and go home. I dried my son off first and dressed him then I stood him beside his push chair and said, "Don't move." Yes I know, telling a two year old not to move - I should have known better.
I then dried and dressed my daughter. When I turned round, my son had gone. I ran up the steps just as he was about to walk through a gap in the beach huts much further along the prom - and right behind him was the guy who had been watching them.
That scene is imprinted on my memory like a photograph. I could even describe the guy to you, every thing he was wearing, his scruffy dark hair, his height - his caramel coloured leather jacket (on a hot day!).
I think everyone on the beach and prom heard me yell. Heads turned. Thankfully my son heard too - turned around and came back. The man hurried on through the gap and disappeared.
The thing is, if I hadn't looked up when I did, I wouldn't have known which direction he'd gone in or where to start looking. It makes my blood run cold when I think about it. And this happened when I was acutely aware of danger. I still managed to almost lose him.
Maybe the guy really was just an innocent bystander. But surely an innocent bystander on seeing a two year old wander off would have told the child's mother, not walked off after him.
Around that time a man had been approaching children outside my daughter's school. The police were "aware" of him.
Those few seconds have haunted me for years. The what ifs and what could have beens.
I was just so very glad when I heard the news that they'd found that little boy safe and well.
