A 40-year-old man has been remanded in custody after appearing in court charged with the murder of one woman and the attempted murder of two others.
Kiesha McKenzie, 28, was stabbed at a flat in Brixton, south London, on Monday and later pronounced dead at the scene.
Police were called to the property in Tilson Gardens at 7.10pm, where they found that the dead woman's 17-year-old sister, Saffron Yeboah-Simpson, had also been stabbed in the head and hands.
She remains in a serious but stable condition in hospital.
Half-an-hour earlier, Joan Wade, 46, was repeatedly stabbed at another flat in nearby Redlands Way. She is in a critical condition in hospital.
Police believe a young boy was at each address when the attacks occurred, but that neither was injured.
Wearing a grey T-shirt and white trousers, Brooks, of Redlands Way, Brixton, spoke only to confirm his name, address and date of birth during the two-minute hearing at Camberwell Magistrates' Court.
He was told he will appear at the Old Bailey for a further hearing on Friday.
No details of the case were given. The victims were named in court documents.
Brooks was arrested shortly before 1am on Tuesday as he travelled on a bus in Leigham Court Road, just over a mile from where the women were stabbed.
