Police have charged a man with murdering a social worker who died after stumbling into a cafe in Perth’s southern suburbs with serious neck injuries. It is alleged the 50-year-old woman, who was reportedly working in the hours leading up to the attack, was stabbed in the neck at a Rockingham unit on Saturday night. She then sought help at a nearby Dome Cafe on Kent Street. Cafe staff helped administer first-aid to the woman before she was taken to Fiona Stanley Hospital, where she later died. Police said Homicide Squad detectives today charged a 37-year-old man from Rockingham with one count of murder. The man was arrested on Saturday night and is set to face Rockingham Magistrates Court later today.
