Semina Halliwell was a 12-year-old girl with autism who alleged she was raped by an older boy who attended the same school as her and had groomed her over Snapchat into secretly meeting him. Her mother, Rachel Halliwell, contacted the police after Semina broke down and told her what had happened following a severe incident of self-harm. Three months after the initial complaint was made, during another interview in the familys living room regarding the rape and harassment, Semina said "Ive had enough of this" and went upstairs. Semina had gone to take the medication which would kill her, consuming well above the lethal dose of a toxic drug used to treat a chronic condition. After the police had left, the family discovered the empty medicine packets and Semina was taken to hospital in an ambulance. Over the next few days, she would be placed in an induced coma and suffered multiple organ failure before dying.

Seminas tragic case was raised in the media, and her mother has become a vocal campaigner against online bullying. A plaque was unveiled at the Botanic Gardens in Southport to honor Seminas life, which Rachel said was her "favorite place in the world". However, the heartbroken mother will have to wait more than two years for answers surrounding the death of her 12-year-old daughter.
