Start some more breaking news for you this morning. We're just hearing that a search is underway for a three-year-old British girl who's got missing in the Algarve area of Portugal and she went missing last night.

Hundreds of people have been searching for the girl.

I cannot love Marlon More than I love her. I would never have taken a risk. It was something that wasn't even a decision. That's how safe it felt.

We had to suggest that we weren't going to be safe. We were down in 58 yards away. We were making regular checks. We were going into their apartment all this quiet every night.

If we had thought it was unsafe for a minute, if there was any conscious element that somebody was going to go into that apartment and steal your child, then of course we wouldn't have done that.

Hello and welcome to Real Crime Profile. This is Jim Clementi, retired FBI profiler, a former New York City prosecutor and writer producer of CMES's Criminal Minds. With me today is...

Laura Richards, Criminal Behavioral Analyst, formerly head of the Homicide Prevention Unit, a New Scotland Yard and founder of Paladin National Stalking Advocacy Service.

And I'm Lisa Zambéri, casting director for CMES's Criminal Minds.

Well, we're going to launch right back into our coverage of the Madeline Mechan case. And again, we're going to, as professionals in this field, Laura and I have to look at all possibilities, the entire spectrum of possibilities in terms of what happened to Madeline Mechan.

So we have to look at it as whether it was a targeted abduction, a random opportunistic abduction, whether it was an accidental death and a false allegation of abduction to cover it or a homicide and a false allegation of abduction to cover it.

And we also have to consider whether she walked out on her own. There's that question Mark, given that she was almost four and had the ability to go out of the door herself.

Absolutely. So it could have been an accidental death as well. So all of those possibilities are things that we're going to explore.

And the way we do it is to first talk about Fick apology, which we've done in the last episode. And now we're going to talk about the timeline. What actually happened?

What are the facts that we actually know? And then as we listen to these facts, as we learn these facts, we develop hypotheses that we then test against the known facts.

And against our experience as professionals in investigating child abduction. So the timeline.

It's one of the most important things to establish the window of opportunity right from the start. And that would mean giving investigators an idea of when the abduction took place.

And that way they will better be able to assess how far an abductor could have gotten from the location where the duct D was last seen.

So the problem in this case is that once it was reported by the parents, they weren't separated and thoroughly interviewed. And their friends that they were there on vacation with were also not separated and thoroughly interviewed.

And in fact, one of the most critical pieces of evidence in the initial investigation was information given by one of their friends, but it wasn't given initially.

Because she didn't understand the significance of it. She reportedly saw a man carrying what looked like a child in pajamas away from the location where Madeline was staying.

But she didn't report it to her parents until after the alarm was raised about Madeline being missing.
