Decade Of Mystery: John Ramsey Speaks

JonBenet's Father Breaks His Silence Since His Wife's Passing, The Karr Arrest

But a closer examination of the evidence doesn’t support that theory. JonBenet was still alive during the strangulation, and probably fought her attacker.

"When she was strangled, she was struggling," Demuth says.

Asked if that is more consistent with a child abduction, he says, "If my conclusions are correct, yeah. That’s child abduction. She’s struggling, she’s breathing, and you’re strangling her. That’s no longer an act of staging."

"It’s murder," Moriarty remarks.

"It’s murder," Demuth agrees. "The conclusion of my summary of the physical evidence is, is a clear conclusion that an intruder committed this crime."

Demuth says the path of an intruder is evident in crime scene photographs: a grate that appeared to be lifted, an open basement window, scuff marks on the wall. During his investigation of the crime, Demuth also put the Ramseys character under the microscope.

"I have never seen two individuals that were more thoroughly investigated than John Ramsey and Patsy Ramsey. I don’t remember one report of the type of pathology that I would expect to see for them to have committed this crime," he says.

In May of 1998, Trip Demuth presented his findings to the Boulder authorities. Four months after his presentation, Demuth says he and his entire team were removed from the case.

But his boss at the time, former Boulder District Attorney Alex Hunter, says Demuth was removed because he was so focused looking outside the Ramsey family that he lost his objectivity.

Demuth regrets leaving the investigation, especially since subsequent DNA tests continued to point away from the Ramseys. But he is most sorry that he never got to treat Patsy Ramsey as a victim.

"Since I believe that the evidence shows an intruder committed this crime, as the prosecutor assigned to that case, she normally would have been my victim who I would have reached out to and held her hand through this process. But I was not given that opportunity," Demuth says.

He says he feels disappointed about that. "But that disappointment is tremendously overshadowed by the disappointment that the killer of this girl has not been brought to justice."

So ten years later, who are investigators looking at now?

"JonBenet’s death needs to be solved. It needs closure, and whoever did it needs to be put away," says Michael Tracey, who spent four years tracking the man he believed was the killer, only to see him walk free.

DNA left at the Ramsey crime scene did not match Karr and child pornography charges pending against him in Sonoma County, Calif., were unexpectedly thrown out of court.

"The charges were dropped because the evidence was lost. That disturbs me," says John Ramsey.

So Karr, who talked about having sex with children, is now back on the streets.

"John be honest. He’s obsessed with your daughter and your family. Are you at all concerned that he could show up here?" Moriarty asks John Ramsey.

"The thought has gone through my mind, absolutely and you know that you can’t live your life in fear. But you know, we tend to be careful," he replies.
