Who killed Lucy Beale

Lucy Beale died because Lucy had an argument with her family Lucy said she was going to work but Lucy went to the flats and a drunk man came in and made her have a nose bleed and her earring came of and Lucy went to her mums jane and they where talking about Denise. Lucy went to Denise's house and she hit her but they thought she had died but she didn't she was asleep. She want to Ian's where everyone was asleep then bobby came down with a jewellery box and rapped it round Lucy's neck and she fell to the floor and bobby was trying to wake Lucy up but he couldn't then bobby phone jane and jane can round to Ian's worriedly she check Lucy's heart beat there was nothing jane check Lucy's plus there was nothing then jane turned around and bobby said what ever she said she was making every on upset and she didn't listen to anyone and then they cried THE END

All bobby wanted was her to listen to what they where trying to say and peter is Lucy's twin pretty shocking is-ant it I'm sad .
