Detectives investigating the murder of Olivia Pratt-Korbel in Liverpool have released footage of another man seen in the area as they continue the search for her killer.

Merseyside Police shared a clip of a man with short hair in a bright jacket, appealing for anyone who saw him, or knows his name, to come forward.

“We believe he may have important information that could help us catch her killer,” the force said on Twitter.

Officers have also revealed that two guns were used in the shooting, in which her mother Cheryl Korbel and the gunman’s intended target, Joseph Nee, were both injured.

The nine-year-old girl was killed after she was shot by the masked attacker who had chased Nee into Olivia’s family home on Kingsheath Avenue in the Dovecot area at around 10pm on Monday 22 August.

Separate CCTV previously released shows what police believe to be the gunman running away from the scene.

A service will be held for the nine-year-old in Liverpool on 15 September, according to a funeral director’s notice.

“Family requested everyone to wear a splash of pink,” the message on the website of Debbie Bennett Funeral Directors said.

“Olivia will be sadly missed by all her family and friends.

“Funeral Mass at St Margaret Mary’s Church, Pilch Lane, Dovecot on 15 September at 11am, followed by a private burial.”

The church, next to her school, held a vigil for Olivia on Wednesday.
