Om vi betraktar den här listan med JKR-exakt:

Böckerna uttrycker inte uttryckligen vem som dödades för att göra var och en av Horcruxes. Vissa av dem kan åtminstone inskränkas i möjligheter, men andra är mycket svårare att avleda vem som dödades för att göra dem från innehållet i böckerna. Det närmaste som vi har till en lista över vem som dödades för att göra varje Horcrux är den här listan, att JKR ger en intervju.

Lady Bella: Whose murders did Voldemort use to create each of the Horcruxes?

J.K. Rowling: The diary – Moaning Myrtle. The cup – Hepzibah Smith, the previous owner. The locket – a Muggle tramp. Nagini – Bertha Jorkins (Voldemort could use a wand once he regained a rudimentary body, as long as the victim was subdued). The diadem – an Albanian peasant. The ring – Tom Riddle Sr.

Då:

Skrämmande Myrtle - dödad av basilisken styrd av Tom Riddle.

Hepzibah Smith - förgiftade, som Tom skyllde på hennes hus-elf Hokey genom att implantera ett falskt minne i Hokey.

“Hepzibah Smith died two days after that little scene,’ said Dumbledore, resuming his seat and indicating that Harry should do the same. ‘Hokey the house-elf was convicted by the Ministry of poisoning her mistress’s evening cocoa by accident.’

‘No way!’ said Harry angrily.

‘I see we are of one mind,’ said Dumbledore. ‘Certainly, there are many similarities between this death and that of the Riddles. In both cases, somebody else took the blame, someone who had a clear memory of having caused the death –’

‘Hokey confessed?’

‘She remembered putting something in her mistress’s cocoa that turned out not to be sugar, but a lethal and little-known poison,’ said Dumbledore. >‘It was concluded that she had not meant to do it, but being old and confused –’

‘Voldemort modified her memory, just like he did with Morfin!”

Muggle tramp - okänd dödsorsak.

Bertha Jorkins - sannolikt dödad med Avada Kedavra, särskilt eftersom den mörka Herrens förmåga att hålla en trollstav nämns.

Den albanska bonden - okänd dödsorsak.

Tom Riddle Sr. - dödad med hjälp av Avada Kedavra, som Tom inramade Morfin Gaunt för, genom att implantera ett falskt minne och använda Morfin's wand för att begå morden.

“The Muggle authorities were perplexed. As far as I am aware, they do not know to this day how the Riddles died, for the Avada Kedavra Curse does not usually leave any sign of damage … the exception sits before me,’ Dumbledore added, with a nod to Harry’s scar.

‘The Ministry, on the other hand, knew at once that this was a wizard’s murder. They also knew that a convicted Muggle-hater lived across the valley from the Riddle house, a Muggle-hater who had already been imprisoned once for attacking one of the murdered people.”
