A photograph resembling the missing Madeleine "Maddy" McCann has gone viral on the internet resurrecting public interest in what some are now calling the "most heavily reported missing persons case" in history. 

Twitter users reposted the photo of Maddy's lookalike, and quickly the photo had gone viral across the globe.

Portugal police who conducted the initial investigations into McCann's abduction still have not found any substantial evidence to trace the whereabouts of the victim or what exactly happened to her. 

Maddy has been missing since May 3, 2007, a few days before her fourth birthday. She was taken from her parent's apartment at Praia da Luz in Algarve, Portugal. 

In other news, Roderick Robinson, a pedophile who was charged of sexual abuse among five to seven-year-old children, has reportedly slipped through the hands of the police, according to a report published by Mirror UK.  Robinson, 77, is said to have been in the area at the time of Maddy's disappearance.

Kate McCann expressed disappointment at the development in the case. 

She said, "The police knew he was in Portugal around the time she vanished, but they let him slip through their fingers." 

It is suspected that Robinson is now living in hiding in a Far East country. 

"They told me they would monitor him. When he fled they didn't even bother telling me. I am so angry he has been allowed to go on the run," the McCann matriarch added.

On a positive note, Maddy's parents have been encouraged by the public's continued interest in their daughter's case. 

A close family member told The New Zealand Herald, "What is encouraging is that it shows everyone is still looking for Madeleine.  That will give her family great strength."
