Following her arrest‚ the woman admitted to stabbing the men.
She initially tried to call the police but when nobody answered the police station phone she went in search of her daughter.
The woman said she had taken a knife with her to protect herself.
Cape Town resident Natalie Kendrick said: “We have raised approximately R130 000 and I received donations from people as far as Switzerland and Germany.”
She said she is in contact with the woman’s lawyer and will be transferring the money to a trust fund.
On Sunday‚ EFF general-secretary Godrich Gardee visited the family and offered them legal support.
The party appointed a clinical psychologist to be with the family and promised to monitor the case.
