A £200,00 reward has been offered to find Olivia Pratt-Korbel’s killer.
Nine-year-old Olivia was shot inside her Dovecot home after a man opened fire on another man who burst into the property on the night of August 22.
The man who was chased into the house and suffered a bullet wound remains in hospital.
Detectives have made a total of nine arrests in connection with the schoolgirl’s murder but no charges have been brought as yet.
Crimestoppers are hoping that a new record reward will help to convince more people come forward with information that will catch Olivia’s assailant.
A private donor put forward £100,000 which was matched by the independent charity’s founder Lord Ashcroft, who had made an initial pledge of £50,000.
“This case has been incredibly shocking, not just for those who are directly affected, but also for Liverpool and the nation as a whole,” said Lord Ashcroft.
“I am delighted that with the support of a private donor, Crimestoppers can now offer a record £200,000 for information to catch Olivia’s killer.
“A precious young life has been lost so we need every effort to find those involved in this appalling killing.”
Anyone with information about Olivia’s killer can contact Crimestoppers anonymously on 0800 555 111 or via their online form.
Information passed directly to police will not qualify for a reward.
