There has been an intriguing new development in America's most notorious cold case, the 1996 murder of JonBenét Ramsey.
They reportedly believe he may be able to shed new light on JonBenét's final hours.
"Something has come about in this case where they need either his corroboration or something that he may have hidden away in his memory," says author Larry Schiller.
Schiller wrote a best-selling book about the JonBenét Ramsey case titled Perfect Murder, Perfect Town.
"He may have some knowledge that will link other elements that have now come to the surface either by technology or some bit of information," explains Schiller.
Burke, a recent college graduate, is not a suspect. In 2008 he and the rest of the family were formally cleared of any involvement in the murder by DNA evidence.
A Ramsey family lawyer told INSIDE EDITION, "Two members of the Boulder Police Department gave Burke a business card and invited him to contact them if he had any further comments to offer."
6-year-old JonBenét's body was found in the basement of the Ramsey home in Boulder on Christmas Day 1996.
The last major break in the case came in 2006 when John Mark Karr claimed to be present when JonBenét was murdered. Police say his claims were part of an elaborate fantasy.
"There's no urgency to catch the killer, but they'll catch him," says Schiller.
Burke Ramsey's attorney went on to say his client would only be helpful as a witness in "investigating or prosecuting the third party intruder who murdered JonBenét."
