A coroner has called for "root and branch" gun licensing reform after ruling three women shot in a house in County Durham were unlawfully killed.
Michael Atherton, 42, shot himself, his partner Susan McGoldrick, her sister Alison Turnbull and Ms Turnbull's daughter Tanya on New Year's Day 2012.
Nicholas Long, of the Independent Police Complaints Commission, said the investigation identified poor practices within Durham Constabulary which reflected woeful record-taking.
