The investigation into the suspected murder of Anita Rose, who died after being found injured while walking her dog in Brantham, Suffolk, continues to deepen. Police have cordoned off two additional areas of interest and are actively searching for a pink waterproof jacket that Rose was wearing at the time of the attack. Three individuals have been arrested in connection with her death, including a man in his twenties and two others who have since been released on bail. Despite a post-mortem examination failing to determine the cause of death, authorities are treating the case as a murder investigation. Detective Superintendent Mike Brown reassured the community of their safety and urged anyone with information to come forward. Community members, including local clergyman Reverend Chris Willis, have expressed support for the police efforts and have held moments of silence in remembrance of Rose.
