A crime expert who has analyzed the high-profile case of missing British girl Madeleine McCann claims the three-year-old was not abducted.

Investigative criminal profiler and "Profile of the Disappearance of Madeleine McCann" author Pat Brown told news.com.au that Scotland Yard bungled the investigation and slammed the crime fighting agency for “wasting time and money” on Madeleine’s case.

“Madeleine is dead,” Brown said.

“There’s no point spending all of this money as nothing they do is going to make that child alive.”

While profiling the case, Brown developed a theory about what happened to Madeleine before her disappearance in Portugal.

“When I do a crime scene analysis it is a theory based on evidence to then be given to police and used to look for more proof and evidence suitable for prosecution,” she said.

“When I analyzed (Madeleine’s) case, it led me to believe evidence does not support an abduction.

“An abduction was extremely unlikely based on the amount of time, evidence at the scene, and every other shred of evidence there has ever been.”

Brown said Madeleine most likely died an accidental death that was “covered up”.

“The evidence supports the theory of an accident occurring through neglect and possible medication,” she said.

“It’s my belief the body was moved to a desolate location and will never be found.”

Kate and Gerry McCann have always denied any involvement in her death and vowed to “never give up” hope of finding their daughter.

“As a parent of an abducted child, I can tell you that it is the most painful and agonising experience you could ever imagine,” Kate McCann wrote on the couple’s ‘find Madeleine’ website.
