A weapon used by the gunman who killed Olivia Pratt-Korbel may have malfunctioned during the shooting, a firearms expert has told a court.
Thomas Cashman, 34, is accused of murdering the nine-year-old and injuring her mother, Cheryl Korbel, 46, at their home in Dovecot, Liverpool, as he chased another man, Joseph Nee, on August 22 last year.
