The case hit headlines then because the dead included a 14-year-old girl Anekha, who was allegedly sexually exploited after a family friend Latha Nair promised her roles in films and TV serials.
The CBI court ordered a fresh probe after dismissing the report of the CBI team that concluded that Anekha was sexually exploited by her father.
The new directive from the court came after Anekha's uncle filed a petition.
