Mohammed Yassin Yusuf, 32, attacked Amoe Seline Stevens, 64, at the address they shared. Yusuf’s wife had left him at home with her frail mother, a pensioner who had suffered a stroke, resulting in her mobility and speech being severely impaired. Yusuf locked himself in his mother-in-law’s bedroom and sexually assaulted her, which only ended when a registered caregiver arrived to get Mrs Stevens ready for bed.
UK Met Police (h/t Anant P) The caregiver became suspicious as Mr Yusuf rushed from the bedroom to his kitchen with blood spots on his hands and shirt. When she entered the bedroom she saw Mrs Stevens slumped in a recliner chair with blood smeared across her legs and a pool of blood on the floor.
As she attempted to challenge Yusuf in the kitchen she realized he was trying to clean the blood from his hands and clothes. She quickly left the property and called for an ambulance and police.
Mrs Stevens was taken by ambulance to St Mary’s Hospital in Paddington but died from her injuries within hours. A post-mortem examination revealed that she had haemorrhaged after suffering multiple internal injuries. Yusuf was arrested and subsequently charged on 19 October 2013 with the murder of his mother-in-law.
Detective Chief Inspector, Noel McHugh, who led the investigation from the Homicide and Major Crime Command (HMCC), said: “This was a truly horrendous crime committed against a vulnerable and defenceless woman. “We believe Yusuf had assaulted Mrs Stevens on multiple occasions but due to her disabilities she was never able to communicate with her family and expose his sickening actions. We also believe that Yusuf is sexually deviant and may well have tried to target other women in his past.
