Four Metropolitan Police officers are under investigation for misconduct after failing to protect Naomi Hunte and Fiona Holm, both of whom were murdered by Carl Cooper, a man they had reported for domestic abuse. Cooper, 66, was convicted of Hunte's murder on Valentine's Day 2022 and is serving a life sentence; Holm's body has never been found. Both women had previously complained to police about Cooper's violent behavior, with Hunte expressing fear of being stalked just months before her death. Despite being arrested for an assault on Holm in April 2023, Cooper was not charged, raising significant concerns about police handling of domestic abuse cases. A review of Holm's complaint indicated that a more thorough investigation could have uncovered key witnesses. The Metropolitan Police have acknowledged their mistakes in dealing with the case and expressed condolences to the victims' families.
