WHY did a British man wait two years before coming forward with possibly crucial evidence about missing Madeleine McCann?
If little Madeleine is dead, the blood must be on his hands.
This man who wishes to remain anonymous has unleashed a search for
an Australian woman who may know something of the little girl's
disappearance.
But it is two years too late. The man who could have saved Madeleine - but didn't - should now hold himself responsible.
What possible reason could he have for failing to tell police he met
a woman who sounded Australian who asked him "Have you got her? Have
you got the child?"
He got a good look at the woman, heard her speak Spanish and saw her
head off in the direction of the marina. All this happened within a few
days of Madeleine's disappearance and could have been a crucial tip in
tracking her abductors.
And yet he said nothing, scared his wife would think he was chatting up the woman in question. What a dirt bag.
Not only did he jeopardise Madeleine's return, he also harshly
judged his wife, who surely would have understood there were bigger
issues at stake.
The man's evidence, passed on to investigators only recently, has
sparked an international hunt for the Australian (or New Zealand or
South African) woman that is both divisive and distressing.
All sorts of women are being singled out for their superficial resemblance to the identikit woman.
Perth woman Rhonda Wyllie, whose yacht was moored in Spain at the
time Madeleine disappeared, is just one who has been named and is
reportedly "devastated".
But I'd prefer innocent people were identified - and cleared - if it means there's a chance of Maddie being found.
But the reality is that as each day passes it is less likely she will be.
The British man would have known this and did nothing for two years. No wonder he wants to stay anonymous.
The tip reflects the heartache that has followed this case every
step of the way. Every time we hear of a new lead we hardly dare to
think that maybe, just maybe, Madeleine is still alive and could be
found.
As a mother with one child the age Madeleine was when she
disappeared and another the age she is now, I'm particularly affected
by the story.
It could be my husband and myself living the nightmare of the McCanns. It could be our daughter who is missing.
Spurred on no doubt by the guilt of leaving their children alone
while they went to dinner, Kate and Gerry McCann have never stopped
searching for their beautiful girl. Some have questioned the point of
the McCanns using the public to find her. It's labour-intensive and
expensive, with every plea generating hundreds of possible leads to
assess.
It has also come at a great personal cost, particularly when they
were viewed as suspects for a short time. But what choice does the
family have? Two years on and there's no official search for her still
going. Portuguese and British police have given up.
Rationally, it is most likely that after this amount of time she is dead.
And yet stranger things have happened. Natascha Kampusch, of
Austria, survived eight years of captivity in an underground cell after
being abducted in 1998.
And in 2002, 14-year-old Elizabeth Smart was abducted at knifepoint
from her Utah bedroom in the middle of the night while her parents
slept.
A huge investigation failed to find her, but nine months after she disappeared she turned up alive.
Remember the abduction of three-week-old baby Montana in Melbourne in 2004, snatched from her mother at a supermarket?
She was found a few days later by chance after a granny jogging by
heard her cries from inside a derelict building. The passer-by, a
seasoned babysitter, knew the cries of a baby in distress and was smart
enough to act immediately.
So it does happen. It can happen.
Our heart leaps at the thought of fresh evidence and we continue to
wonder: Where is Maddie? What is she doing now? Is she happy? Is she
being treated well?
There are people out there who can answer these questions.
They must come forward and help save this little girl.

But why don't people come forward??Their own fear? Probably.
For whatever reason they feel the best thing to do is keep shut and carry on as if nothing as happened because that way they don't have to be involved.Yet deep down do they get riddled with guilt?They must do to come forward 2 years later.

How long can a person go without telling?Forever?...... ive seen it done before in different situations where a person thinks that talking about something they know might end up getting involved in something they will later regret.That keeping quiet might prevent them being dragged into a police investigation and getting bombarded with all sorts of deranged feelings and fears of whats going to happen etc.Thing is what they have to realise is that while they aint talking and while they are sitting on the info they hold they are not only goign to be riddled with what ifs for the rest of their lives they are also hurting the person/s that need their help.

Nowt so queers as folk Claire.

Could be a very good reason why he couldn't come forward in his own eyes. Lets be thankful that he did in the end do the right thing.
