A nine-year-old girl was shot dead in Liverpool last night as she stood behind her mother who was trying to stop a gunman entering the family home.

Olivia Pratt-Korbel died after the shooting when a 35-year-old man, unknown to the family, ran into the terraced house in Kingsheath Avenue, in the Dovecot area of Liverpool, in an attempt to get away from a shooter, Merseyside Police said.

Her mother Cheryl Korbel, 46, was shot in the wrist as she tried to close the door on the gunman while her nine-year-old daughter stood behind her.

The man who had entered their home suffered gunshot wounds to his upper body and, as Olivia lay dying, was picked up and taken to hospital by friends driving a dark-coloured Audi.

Speaking at a press conference today, Merseyside Police Chief Constable Serena Kennedy said: "We will not rest until those who are responsible are put behind bars.

"I can guarantee that no stone will be left unturned."

The incident happened exactly 15 years after 11-year-old Rhys Jones was fatally shot in Croxteth, Liverpool.

Detective Chief Superintendent Mark Kameen said Olivia had been at home with her two older siblings and mother when Ms Korbel opened the door after hearing gunshots fired outside.

He said a figure, wearing a black padded jacket, a black balaclava with a peak, dark trousers and black gloves, fired shots at two men walking along Kingsheath Avenue, causing both of them to run away.

One of the men ran towards the open door of Olivia's home and forced his way in, Mr Kameen said.

"As that was taking place the person with the gun has followed the male to this property," he said.

"That person has also tried to force entry to the property and has managed, it would appear, to put their hand through the open door as Cheryl continued to try and close it.

"A shot has been fired which we believe has hit Cheryl, injuring her and then fatally wounding Olivia. Olivia at that time, we believe, was stood directly behind Cheryl."

Olivia was taken to Alder Hey Children's Hospital by officers but later died.

The Audi used to transport the injured man has since been seized, police said.

Mr Kameen urged the person responsible to come forward.

He said: "My appeal is to the person responsible for this horrendous attack on a nine-year-old schoolgirl to recognise the pain and anguish that this has caused to her family.

"I want that individual to hand themselves in."

Ms Kennedy added: "This is a shocking and appalling attack which will reverberate around our communities, and I want to take this opportunity again to appeal to anybody who knows who was responsible for this attack to please come forward and give us those names.

"We need to find all who are responsible for this - not just the gunman, we need to find who supplied the weapon and who arranged this terrible incident."

The force also appealed to the "criminal fraternity" in Liverpool for information, adding that the incident "crosses every single boundary".

Appeal to identify killer

Chief Constable Kennedy appealed to "the criminal fraternity" to "examine their consciences" and identify Olivia's killer.

"They will have vital information that can help us," she said.

"The killing of a nine-year-old child is an absolute tragedy and crosses every single boundary, and I would urge them to do the right thing so we can put this person behind bars."

Ms Kennedy also warned against a "no-grass" culture taking hold in the community, pledging to protect those who spoke to the police.

"If people are frightened to come forward, we can have those conversations in confidence," she said.

"Please come forward and let us work with you, so that you can feel confident to give us that information and not feel frightened around the reprisals."
