JonBenét Ramsey was 6 years old when she was murdered in her home in 1996.
There were just three other people known to be in the home at the time: JonBenét's parents and her 9-year-old brother, Burke.
While her parents have spoken publicly about the murder, Burke has not.
Now, 20 years later, for the first -- and, he says, last -- time, Burke spoke about his sister's murder on an upcoming episode of "Dr. Phil."
Burke described the morning his sister went missing. He said he remembers his mother running into his room, shouting, "Oh my gosh" and trying to find JonBenét.
The next thing he remembers is a police officer coming in with a flashlight.
Apparently, when Burke talked about this with Dr. Phil, he was smiling, which struck the host as odd.
Dr. Phil spoke about the interview on the "TODAY" show. He said,
People are going to be very interested in his demeanor, and they're going to find his demeanor atypical. He might be talking about some pretty dark aspects of this story and smiling while he's talking about that.
Burke and his parents were prime suspects for the murder, which garnered national attention focusing on the pristine beauty pageant photos of JonBenét.
But they were officially cleared of suspicion in 2008 when DNA from the victim was shown to belong to an unidentified man. The case is still unsolved.
JonBenét's murder and the massive media attention was, of course, a life-changing experience for Burke.
For a long time, the media basically made our lives crazy. It's hard to miss the cameras and news trucks in your front yard. And we'd go to the supermarket sometimes and there'd by a tabloid with my picture, JonBenét's picture, plastered on the front. They would follow us around. Seeing that as a little kid, that was just kind of a chaotic nightmare. So I was pretty skeptical of any sort of media. It just made me a very private person.
Burke said he's speaking out now because it's the 20th anniversary and he doesn't "want anyone to forget."
