When they die.
Emos
Emos
Hannah was a happy 13-year-old until she became an 'emo' - part of a sinister teenage craze that romanticises death. Three months later she hanged herself. Here, her devastated mother tells other parents: No child is safe
On the night before she died, she came into their room, kissed her father Raymond on the cheek and cheerfully told him: "I love you, Dad."
The following day Hannah's mother Heather went to check on her daughter and found her hanging by a tie from the top rail of her bunk bed
A trans-Atlantic import, its followers dress in black, favouring tight jeans, T-shirts, studded belts and sneakers or skater shoes.
Hair is all-important: often dyed black and straightened, it is worn in a long fringe brushed to one side of the face.
Music also plays a critical role.
Emos like guitar-based rock with emotional lyrics.
American bands such as My Chemical Romance, Good Charlotte and Blink 182 are particular favourites.
Only after her death would they discover how she had secretly chatted online to emo followers all over the world, talking about death and of the "black parade" a place where emos believe they go after they die.
A check of Hannah's home page on social networking site Bebo revealed her pseudonym, Living Disaster, and that she'd decorated it with a picture of an emo girl with bloody wrists.
Another picture showed a child's exercise book scrawled with the words: "Dear Diary, today I give up."
My Chemical Romance made it to No.1 in the UK chart with Welcome To The Black Parade in October 2006 - the 'black parade' is a place where all emos believe they will go when they die
