"The day we got the knock on the door to say my brother had passed, I don't think there are any words to describe that type of pain. A lot of myself died when he died.""Henry was the most wonderful, funny, handsome, kind, precious, smart boy. He lit every room he walked in. As the eldest of four siblings, watching my younger brothers and sisters grieve the loss of their big brother is a pain layered on top of my own."Whenever I'm having a hard day, the only place I want to be is at Henry's grave. It is the place where the reality of his loss hits the hardest but the only place I am close to him."‌"I feel sad for those who never got to experience life with Henry, even though it was short.

She said of her grief: "the pain is beyond anything I knew existed."Henry's father Mark also said in his victim impact statement: "There is a Henry-shaped hole in our family forever, and nothing will heal that.

He had so much life ahead of him, so many plans, and so much love to give."In another touching tribute, she said: "Henry deserved so much more from this life. Henry and his family have been let down so badly. This could happen to anyone, anyone's child. Henry we will fight until the end for you. The world will know your name.‌"You changed our lives for the better for being a part of it, I believe you will now go on to change the lives of others by the legacy you will leave."

Henry had a big heart and an even bigger personality, and he will be incredibly missed by everyone."On a post that Southampton University made in tribute to Henry, one parent who knew Henry wrote that he was a 'wonderful' young man.

You had a wonderful son who will always be in your hearts."
