"I guess I kinda like to avoid conflict," Burke tells Dr. Phil. "Part of me doesn't wanna know what's going on."
"The first thing I remember is my mom bursting in my room really frantic," the now 29-year-old adds. "The next thing I remember is a police officer coming into my room, shining a flashlight."

JonBenet's murder remains one of the most perplexing and highly discussed unsolved mysteries in American history. Her parents, John and Patsy Ramsey, made the first call to police after she disappeared, claiming to have found a note demanding $118,000 in ransom.
Hours after police completed a search of their home, John found his daughter's body. John and Patsy -- who died in of ovarian cancer in 2006 -- were primary suspects for over a decade until police cleared them, as well as Burke, of any wrongdoing in 2008.
