Lifetime has released the first trailer for their upcoming JonBenét Ramsey TV movie, “Who Killed JonBenét?”

The cabler has also filled out the cast for the telepic, casting the young actor to play JonBenét’s brother, Burke Ramsey, who will be played by nine-year-old Kiefer O’Reilly. The Lifetime movie will follow the real-life story of JonBenét’s murder, featuring Burke being accused and interrogated.

Burke Ramsey recently gained a re-surge of attention, following CBS’s true crime docuseries “The Case Of: JonBenét Ramsey,” which highlighted a theory that Burke is guilty of his younger sister’s murder in 1996.

O’Reilly’s credits include the CW’s “Legends of Tomorrow” on which he plays Jonas, Rip Hunter’s murdered son. He also voices a main character in the animated film “Howard Lovecraft and the Frozen Kingdom.” In the Lifetime movie, O’Reilly will star alongside previously announced cast members Eion Bailey, Michel Gill, Julia Campbell and Payton Lepinski as JonBenet.
