Mystery surrounds the bloody murder of Smit, who had been found in her Theresa Park home with her throat slit, her hands severed, and a glass bottle sticking out from between her legs.

Smit had stayed away from school with an ear infection on the day of her murder, and appeared to have opened the door for her attacker.

Three “persons of interest” became central to the case, including her father.

Another was a friend of hers, Damian Treeby, who was dubbed “the vampire” for his name on messaging application Mxit.

Smit's boyfriend, Nico Venter, was accused of killing her, but the charges were withdrawn.

The inquest previously heard revelations about schoolchildren drinking blood shooters at a vampire party, and how Treeby became friends with a group of high school children that were interested in the occult. One of them was drawn to Satanism.

The inquest was being held as there was not enough evidence to arrest and put someone on trial.
