A gun used on the night of Olivia Pratt-Korbel's murder is linked to two other shootings on Merseyside.
Detectives investigating the schoolgirl's murder have identified two types of gun used by Olivia's killer on the night of August 22. The first gun is a .38 revolver, which was used to kill Olivia.
The second gun, a Glock-type self-loading 9mm pistol, was used in three separate shootings on Merseyside over the last two and a half years, including the attack on Kingsheath Avenue that led to the murder of Olivia.
