Detectives were called to the property in Great Waldingfield, near Sudbury, on Thursday morning. After forcing their way inside, they discovered the bodies of a 44-year-old woman and her 12-year-old daughter. A man who was also inside the property, and known to the victims, was found with serious injuries. He was arrested on suspicion of murder before being taken by ambulance to Addenbrooke’s Hospital, Cambridge, where he remained in a critical but stable condition. Neighbors on Great Waldingfield’s Heath Estate had to be evacuated from their homes after a gas leak was discovered at the property.

Witness appeal

Police said the two victims and the man in custody were known to each other and, due to previous contact between the force and the family, the matter has now been referred to the Independent Police Conduct Office. In a statement, a spokesman for Suffolk Police said: “Detectives believe this is a contained incident with no wider threat to the community and understand all three men were known to each other. “This afternoon a post-mortem examination was carried out at the Home Office in relation to the 44-year-old, which concluded that her cause of death was pressure on the neck. “The Home Office post-mortem on the 12-year-old girl is expected to take place next week.” The spokesman added: “Due to the fact that there was previous (but not recent) contact between the victim and Suffolk Police, the matter has been referred to the Independent Police Conduct Office for their assessment, in accordance with agreed protocols.” Suffolk Police are also appealing for witnesses to come forward.
