Semina was a "happy little girl" until she started self-harming at Stanley High school, according to her mother rachel Halliwell, who spoke at an inquest held monday at Bootle Town Hall.
She informed her mother in march 2021 that she had experienced sexual assault in january of the same year.
In tears, Ms. Halliwell told the coroner's court, "It destroyed her physically and mentally." She transformed into someone else.
She said that Semina first retracted the complaint after telling the police about the event.
Ms. Halliwell remarked, "She felt like she wasn't believed."
"I think it is not what any woman or child who has experienced sexual assault or rape needs to hear," she continued, adding that the 12-year-old girl had autism. "It is going to take 18 months to two years to go to court, do you really want it hanging over your head?"
She said that when the report was filed, the police, social services, and the school did not provide adequate assistance.
Ms. Halliwell said, "She'd still be here today," when asked what may have changed if Harriet Johnson had given greater help, speaking on behalf of the family.
She said that after Semina made the accusation, she was harassed and assaulted three times.
However, Ms. Halliwell stated that Semina decided that "enough was enough" and that she wanted to move forward with the lawsuit.
The inquest was informed that police were scheduled to interrogate her in June.
"She was determined to do this, but she just couldn't handle the chaos that was going on in school and outside of our home in the interim," Ms. Halliwell stated.
Semina remarked, "I've had enough of this," while downstairs with police officers who had been to the house to see CCTV footage before taking the pills.
"I assumed that she had had enough of the police being in the house," her mother stated.
After her brother discovered empty pill packets on the floor, he took Semina to Liverpool's Alder Hey Children's Hospital, where she passed away on june 12, 2021.
Mark Deakin, a consultant pediatrician, stated in a statement submitted to the court that Semina asked him if she was going to die.
He said that she informed him on june 10 that she merely took the pills to "make her sleep for a couple of days" and that she regretted taking them.
Seven days are allotted for the inquest.
