Videos of Semina being bullied and violently attacked were directed at the family on social media following the funeral, as were messages celebrating Semina's death, her family told Sky News, while vandals also trashed her grave.
"The evidence has not revealed that real and immediate risk to Semina's life was known to state agencies which would have made her death preventable by the state," the coroner said.
An inquest into the death of a 12-year-old girl who took a fatal overdose after telling police she had been raped by an older boy at her school has found "no evidence" that her death could have been prevented by authorities.
Semina's mother, Rachel Halliwell, claimed Semina had been repeatedly harassed after reporting the older boy, who she said had groomed her on Snapchat.
Semina Halliwell, who had autism, died in June 2021, after taking a toxic drug used to treat a chronic condition at her family's home in Southport, Merseyside.
