The gunshot that killed nine-year-old Olivia Pratt-Korbel changed the community in ways that will be felt for years to come.
But one change that will be welcomed by many parents and residents living in the borderlands between Knowsley and Liverpool is a new focus and determination to break the cycles of violence that snatched Olivia's life.
For residents living in those communities, more police on the streets is a good start to forcing out the criminal groups that have caused so much misery. Kellie Owens, one of the directors of The Gate community centre in Page Moss, was one of thousands in Merseyside left in a state of shock when Olivia was killed in her own home on August 22.
