In a preview of an interview with Dr. Phil McGraw, Burke Ramsay—the brother of slain six-year-old pageant queen JonBenét, whose murder captured the country's attention in 1996—smiles throughout his recollection of the moment his parents realized JonBenét went missing.

McGraw notes that 29-year-old Ramsey, who works remotely as a software engineer and has not had much interaction with the outside world, is "socially awkward." Both Burke and his parents John and Patsy Ramsey were suspects in the murder of JonBenét, who was found strangled in the basement of her parents' Boulder, Co. home the day after Christmas in 1996.

In a different clip posted by Dr. Phil's show on Friday, Ramsey talks about how attention from the media impacted his life growing up.

"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 be a tabloid with my picture [or] JonBenét’s picture plastered on the front or they would follow us around," Ramsey said. "Seeing that as a little kid is just kind of a chaotic nightmare, so I was pretty skeptical of any sort of media, like, it just made me a very private person."

Ramsey was 9 years old when his sister was murdered; he says he remembers his mom "bursting in my room, really frantic, saying, 'Oh my gosh! Oh my gosh! Oh my gosh!' running around my room—now I know looking for JonBenét."

Investigators have reviewed or investigated over 20,000 tips, letters, and emails regarding the case, according to the New York Daily News

It's the first time in the 20 years since JonBenét's death that Ramsey has spoken publicly. He says it will be his last.

The full interview will air Monday.
