Cops turn up the heat on the brother of murdered JON BENET RAMSEY.

AP reports that JonBenet Ramsey’s older brother, Burke, is among those law enforcement in  Colorado will re-interview in a new  investigation into the child beauty queen’s chilling murder that shocked the nation 14 years ago.

Now  23 years old, Burke, who was 9-years-old when Jon Benet was found dead in December 1996 at the family’s Boulder, Colorado home is being queried again by cops. 

In 1999, nine years after the rest of his family was exonerated by authorities, Burke was cleared of any wrong-doing in the tragic murder of his six year old sister. 

The Boulder Daily Camera reported Ramsey family attorney Lin Wood said a police detective recently "met with Burke and gave him a card and said, ‘If you want to talk to us, here’s how you would contact me.’"

An advisory committee which met last year to review all testimony and evidence in the ice cold case has recommended cops talk again to Burke and other "persons of interest".

Police Chief Mark Beckner
declined to elaborate on this newest attempt to solve the harrowing mystery.
