Stacey Slater was revealed to have killed him on Friday 19th.
No one knows who killed Archie Mitchell, but we can guess...If you want to discuss who you think might have been the killer, please use the 'discuss' option on the left hand side of this answer box. Below are people who could have killed Archie:
Sam: Because of the Christmas episode, it could be her, however Archie has helped Sam if you remember he sorta helped her and she seemed to think that he was nice and kind to her. Even though she was in a state and was saying that she was going to go over to him and make her Mum proud, would she really kill someone who had been kind to here?
Roxy: It is unlikely to have been Roxy because she was with Amy, however it is possible that she left Amy with someone else or Amy was with her while she killed Archie. Roxy could have wanted revenge on Archie for what he's done to her family - recently and in the past. Also, Archie is still Roxy's dad, and he does still love her and she probably still loves him.
Janine: She has got a very big motive.
Ronnie: Given Ronnie's mental state and having had both her children killed by Archie, there is a high chance that she could have killed Archie. Also, Archie is still Ronnie's dad, and he does still love her and she probably still loves him.
Phil: It wouldn't be the first time he had killed someone, but he was drunk that night and so it is unlikely that he would have been able to lift the murder weapon.
Ian: He hated Archie but he's unlikely to do something that would cause trouble for his family. He also seems like too much of a wimp to kill someone.
Peggy: She has it in her to kill him as he has done so many things to her and her family including lying, killing her granddaughters and stealing her pub. She has revenge in her eyes for all he has done.
Jack: He could have killed him because even though Archie hasn't actually done much to Jack himself, he has hurt his lover and mother of his child. He might also have thought that murdering Archie could let him get back with Ronnie as she would love him for killing Archie.
Bradley: He doesn't know Archie that well but his girlfriend knows him very well and because of that she's now pregnant with his baby! Bradley has been through a lot lately and so he could have just let out all his anger on Archie. It does seem like his sort of style murder (throwing something statue rather than make him suffer).
