A former district attorney lead investigator on the JonBenet Ramsey murder case says he's still hoping the case will be solved.
James Kolar has written a book saying evidence raises questions an intruder was responsible.
According to the Boulder Daily Camera, Kolar doesn't say who he thinks killed JonBenet. The 6-year-old beauty queen was found dead in 1996.
Police initially suspected family members, but a grand jury investigating the case was dismissed without indictments in 1999, citing a lack of evidence. Other investigators have said an unidentified intruder may have hidden in the house before the murder was committed.
