App will help find missing children
But what if we had have known these faces as soon as they had disappeared - would there have been a different outcome?
One Jersey businessman believes so.
He has invented a mobile phone app designed to help find missing kids.
Stephen Fern says the concept is simple.
If you lose your child you send an alert to people who have the Lost Kidz app.
Mr Fern said: "When I press that button, everyone within about a square kilometre will actually receive that alert with a photograph of the child and a description.
"Basically if they have the child in front of them they can phone me directly or if they've got information that maybe they've seen the child or seen the child in a car or with somebody else they can text that information to me."
A child going missing can be a parent's worst nightmare and many think using technology nearly all of us have access to would really help.
But some are wary. They have concerns that paedophiles could take advantage of the system.
While Mr Fern admits that is a possibility, he insists we are far better off with the app than without it.
Mr Fern said: "Without the app, that predator can act completely unhindered and unchallenged as they did in the Jamie Bulger case and walk away with your child and nobody even knows that your child is missing.
"With the app, you're pressing the button and you're bringing together the hundreds if not thousands of good people there are in every society who are now on your side."
Mr Fern says this is the first app of its kind.
He is planning to launch it in the US early next month.
