The chief constable of Merseyside has said police know who killed schoolboy Rhys Jones - and it is only a matter of time before he is caught.
The 11-year-old was shot dead as he walked home from football practice in Croxteth, Liverpool, on 22 August.
Despite 18 arrests in connection with the shooting, no-one has been charged.
But Bernard Hogan-Howe said on Radio Merseyside: "If the person is listening , we are confident we know who you are and are building a case against you."
He added detectives were "confident" the killer would be caught.
