Sixteen years after the death of a child in Boulder on Christmas night, the crime remains unsolved.
That murder victim, JonBenet Ramsey would have been 22 years old today.
Ramsey's father, John Ramsey, released a book earlier this year called "The Other Side of Suffering." It recounts how John Ramsey's faith helped him navigate course from suffering to forgiveness, according to ABC News.
While most people know JonBenet for her frilly attire as she competed in pageants, John Ramsey said he remembers his daughter as a tomboy, who loved to hike and play with her older brother, Burke.
"I see her, you know, in shorts and t-shirt and hair kind of scruffy and just kind of a kid," he said.
A former district attorney lead investigator on the case also wrote a book this year. He said the evidence raises questions an intruder was responsible.
"My theory definitely went against an intruder," said James Kolar. "There was strong physical evidence that discounted the intruder theory as it existed."
According to the Boulder Daily Camera, Kolar didn't say who he thinks killed JonBenet in his book called, "Foreign Faction: Who Really Kidnapped JonBenet?"
Kolar did say he is still hoping the case will be solved.
Boulder police told 7NEWS last summer that more than 150 DNA samples have been tested in the investigation. More than 140 people have been investigated as potential suspects, but none could be linked to the crime.
Boulder police took the investigation back from the district attorney's office in 2009 saying they would apply new technology and expertise in hopes of solving the case.
At the time, newly elected District Attorney Stan Garnett agreed that police should lead the investigation again.
"District attorneys prosecute and police investigate," Garnett said. "I have carefully reviewed the state of the evidence in the Ramsey case, meeting with many people both inside and outside of my office. Based on the state of this evidence, no charges can be filed against anyone in this case at this time. Possible leads come in on a regular basis and the Boulder police should investigate these leads. I, in consultation with my staff, will make any filing decision based on the evidence."
JonBenet's mother, Patsy Ramsey, died from cancer in 2006.
John Ramsey, remarried in July 2011.
