Evidence found 30 years ago following the death of 5-year-old Jon Benet Ramsey in her Boulder home is being re-tested by the Boulder Police department at the recommendation of a Colorado cold case review squad. The 5-year-old pageant queen was killed the day after Christmas. She was found in her basement. Her brother John spoke at an annual convention, Crime Con, which was held in Aurora this weekend. Investigators are hoping new technology and breakthroughs in DNA testing will give them new leads to pursue. Ramsey was hit in the back of the head with an object and choked to death.
