Officers went to Lucy’s home at the same time.
“We got that dreaded knock on the door at one o’clock in the morning,” she said.
“They said to me, ‘Do you have a son called Henry?… There’s been an altercation. And unfortunately, your son has passed away’.
“No words, no words can explain that feeling.”
Olivia said she rang her father after hearing the news. “I just remember this scream. It was awful. He screamed ‘My boy, my boy’,” she said.
She now keeps some of Henry’s T-shirts on his bed and told ITV they still smell of him and give her comfort.
But Lucy said she could no longer enter his bedroom because of the memories it holds.
“I can’t go in there,” she said.
Coats now hang over the bedroom door so she does not have to look at it as she passes.
