A man has been charged with murdering his 70-year-old mother who was stabbed to death at her home.
John Cole, 35, was arrested after police were called to reports of violence in Oak Tree Close in March in Cambridgeshire in the early hours of Monday morning.
Wendy Cole was pronounced dead at the scene and her son, also of Oak Tree Close, was charged on Tuesday.
He appeared at Cambridge Magistrates' Court on Wednesday.
Deputy District Judge Samantha Rastogi remanded Mr Cole into custody to appear at Peterborough Crown Court on Friday.
Police said they were treating the death as an "isolated incident" and urged those with information to come forward.
Clothing recycling bins outside the fire station on Wisbech Road were searched as part of the investigation, police said.
