Bobbi Kristina Brown's cause of death is now known, but the Fulton County Medical Examiner has not made the autopsy report public due to a court order.
According to TMZ, police are still on the hunt for evidence that could lead to a homicide prosecution.
They have been looking at Nick Gordon, Bobbi Kristina's boyfriend, almost from the beginning, the website added.
"The Fulton County Medical Examiner has classified the cause and manner of Bobbi Kristina Brown's death based on information available as of Sept. 25, 2015," read the statement posted on the Medical Examiner's website.
"However, a Fulton County Superior Court Order dated Sept. 25, 2015 has been received Sealing the Autopsy Report and ordering the Medical Examiner to not release any further information to the public. The Fulton County District Attorney and Roswell Police Department have been informed of the Medical Examiner's findings."
