Investigators are hoping that new information will help solve the mystery of what happened to Madeleine McCann.

The then- three-year-old British girl disappeared six years ago while vacationing with her family in Portugal.

Scotland Yard is planning to release a computerized sketch of a possible person of interest in the case.

Former prosecutor Wendy Murphy joined America’s News Headquarters to discuss the development.

"I’m not buying it. I think this is more PR than anything," Murphy said. "I think this is all related to a civil suit now underway in Portugal."

The McCanns sued the former police chief for defamation because he wrote a tell-all book.

Alisyn pointed out that the McCanns claim the Portuguese police never took the case seriously.

Alisyn Camerota (news anchor) - Investigators are hoping that new information will help solve the mystery of what happened to Madeleine McCann. She, of course, is the 3 year old British girl who disappeared while on vacation more than 6 years ago. Now Scotland yard is planning to release a new computerized sketch that shows a possible suspect. Wendy Murphy is a former prosecutor and a child advocate. She joins us now. Hi Wendy.

Wendy Murphy (former child abuse and sex crimes prosecutor, now adjunct professor and trial and appellate attorney specializing in crime victims) - Good to be with you

Alisyn Camerota - Finally, finally six years later investigators are releasing a computerized sketch of who they call basically a person of interest, a suspect, that people saw around the vacation condo that night. What took them so long?

Wendy Murphy - Uh, I hope you don't mind if I duck that question because I'm not buying it. I mean I think this is more PR than anything... there's, in my opinion, no new suspect and there will never be a new suspect unless and until the parents answer questions. Remember Kate McCann, poor Madeleine's mom, refused to answer 48 questions...

Alisyn Camerota - (interrupting) ...Now Wendy when was that...

Wendy Murphy - ...and hired a team of lawyers right away ...Ah... this is important ... she hired lawyers right away, refused to answer 48 questions... Things like 'what did you see when you walked into the room where your child was supposed to be sleeping?' I mean I am so not interested in being dragged down a rabbit hole about fake suspects and I think this is all related to a civil suit now underway in Portugal. The McCanns sued the former police chief for defamation...

Alisyn Camerota - (Interrupting) ...because he wrote this book...this alleged tell-all book...

Wendy Murphy - Yes...

Alisyn Camerota - Wendy hold on let me tell you the other side of this because there is a lot of evidence on the side of the parents being completely innocent as well. They say that the Portuguese police never took the case seriously. They never did the kind of investigation that we certainly would have done here in the United States which is talking to other people at the vacation...at where they were vacationing in Portugal... Furthermore Kate and Gerry, the parents, have appealed to their country's Prime Minister, David Cameron for help on this investigation. Is that something you do if you are trying to stay under the radar and you feel guilty?

Wendy Murphy - Do you hire the nations biggest defence attorneys, PR firms and refuse to answer questions? The Portuguese police did a very good job and the PR, misinformation, especially in this country, is doing a disservice to this poor little girl who is dead, I believe, and has no voice. The libel suit currently under-way in Portugal is important because the McCanns sued that ex police chief claiming he lied about them in his book. Now Kate McCann wants to testify, in writing, because she does not want to submit to cross examination. I think this is all related to that and this whole 'we have a new suspect' thing is part of them again trying to distract attention from the fact that as parents of a missing, probably dead child what are you doing not answering questions? Please!

Alisyn Camerota - It's such a tough one... As you know this has gripped our country and Europe to try to find this little girl. When things like Elizabeth Smart put out a book and she's found, she comes home you still have hope that maybe Madeleine McCann is alive and can come home against all odds. Great to see you Wendy. Thanks so much for your theory.
