Bereaved father fights for access to daughter's social media
Mariano's daughter Mia took her own life in March 2021 after suffering abuse and bullying at school and online.
More than a year later, Mariano is still waiting for answers about the events leading up to his 14-year-old daughter's death.
It devastated the family so much that within a few months her mother, Marisa, died from an aggressive form of sudden-onset cancer.
Mariano, from north London, wants parents whose children have taken their own lives to be allowed access to their social media - at the moment, there is no requirement for social media firms to hand over data to police or a coroner without a court order.
