A suspect "remains at large" in the murder of Ashley Dale, the ECHO understands.
So far 15 people have been arrested, including three who have been charged, after the 28-year-old Knowsley Council worker was shot dead in her own home on August 21 last year. Shortly after midnight a gunman burst through the front door of the property in Leinster Road, Old Swan, and fired multiple shots "indiscriminately".
Detectives have said they do not believe Ashley was the intended target of the gunman. The ECHO understands at least one suspect remains wanted for questioning in connection to the case. Merseyside Police declined to comment.
