The "needless loss of life must stop" says a council leader who warns "enough is enough".
Merseyside was shocked to the core after several murders in one week - one of them a nine-year-old girl. On Monday, Olivia Pratt-Korbel was shot and killed by an intruder at her home in Dovecot.
Paying tribute to the young girl who "loved life and all it had to offer", the family said: "Although her life was short, her personality certainly wasn’t and she lived it to the most she could." A 36-year-old man has since been arrested on suspicion or murder and remains in custody. He has also been arrested on two counts of attempted murder.
