She was rumored to have a pact with Satan for decades before she was put on trial because of her claimed ability to heal blood wounds and her good hand with animals, which gave her the sobriquet 'Sotpackan'.
The rumour was, that Anna had cast a spell on the vicar, making him unable to hold the sermon, as a revenge after he fired her.
She was accused of having cast a spell on the villager Nils Jonsson, causing him to experience loss of sight, speech and hearing.
Nils Jonsson claimed that her motive was a conflict between them caused by his refusal to give her tobacco on a Sunday visit she had made to him.
As a witch, she had created wolves by use of magic and ordered them to attack the neighbour's sheep years previous when Jonsson's wife's first husband was still alive, by blowing a horn together with Satan.
[1] She stated that she had been in the service of Satan since her childhood, when her mother had smeared a calf with ointment and flew with her on it through the chimney to Blockula, and that her father, brother and two sisters had also been "tainted by the same sin".
In 1724, several women in Södra Ny socken, Värmland who confessed to have abducted children to Satan was sentenced to be whipped, which was the last time anyone was judged guilty of sorcery in Sweden.
