The trailer opens with a children's choir singing "Silent Night" with a voiceover from actress Payton Lepinski, who plays JonBenet Ramsey.

"I was Little Miss Colorado. This Christmas I would be 26, but to everyone I'll always be six."

Lifetime will premiere the two-hour movie "Who Killed JonBenet?" on Saturday, Nov. 5 at 8 p.m.

This Christmas will mark 20 years since the 6-year-old beauty queen was murdered in her Colorado home. The murder remains a mystery.

Following the movie, Lifetime will air another two-hour special called “JonBenét’s Mother: Victim or Killer?”

The special focuses on Patsy Ramsey, JonBenet's mother, who some speculated could be a suspect in her daughter's murder. She was never charged in the case. They will also reexamine the crime and evidence with modern technology.

Lifetime's special comes a month after CBS aired it's own special "The Case of: JonBenet Ramsey" on the unsolved murder. The panel of special investigators suggested that JonBenet's brother Burke Ramsey may have been responsible for her death.

Dr. Phil also recently interviewed Burke Ramsey on the case. Ramsey again said he did not kill his sister. He also was never charged in the case.
