The 14-year-old girl viewed material about self harm and suicide before she died in 2017.
The father of a 14-year-old girl who took her own life after viewing graphic content online has described her as full of "love and hope and happiness".
"It is sadly all too easy to look back and think of the torment Molly must have endured, the pain she must have experienced, and the isolation she must have felt so deeply."It's all too easy to forget the person she really was: someone full of love and hope and happiness, a young person full of promise and opportunity and potential.
Mr Russell told the inquest: "Just as Molly would have wanted, it is important to seek to learn whatever we can and then to take all necessary action to prevent such a young life being wasted again."A statement read out to the court on behalf of Molly's mother Janet outlined what happened when she discovered her daughter's body.
"I screamed and ran out of the room. Ian came upstairs and I told him not to go into the room, but he did. On a normal day there would be just the coroner, sitting behind his wood panelled desk, slightly raised above the rest of the court. There might be next of kin and possibly a police officer, dealing with the daily administration of deaths which happen unexpectedly.
Senior employees from Meta, the parent company of Instagram and Facebook, and Pinterest, are due to give evidence in person at Molly's inquest.
