A British woman who caused severe head injuries to her seven-week-old daughter has been sentenced to life in prison, after the child later died from complications related to the abuse.Sarah Ngaba, 32, was sentenced at Birmingham Crown Court on Friday after pleading guilty to the murder of her daughter Eliza. The court heard that the infant suffered serious brain and skull injuries in November 2019, leaving her permanently disabled and medically vulnerable, the BBC reports.Eliza died in 2022 at the age of two after developing a respiratory infection. Prosecutors said the infection proved fatal, leading to life-threatening injuries his mother suffered nearly three years earlier.Sentencing, Mrs Justice Brunner said that Eliza had been deprived of the opportunity to live a normal life and concluded that Ngaba had attacked the infant in a fit of rage.“You are a person who loses his temper and throws tantrums,” the judge said. He also said that Ngaba never gave a true account of what happened to his daughter.Ngaba admitted responsibility for causing the injuries but denied murder. A jury rejected his defense and found him guilty after a trial in May.Medical evidence presented during the case showed that Eliza’s injuries were consistent with both shaking and impact trauma. Prosecutor Lisa Hancox Casey told the court that the injuries were caused by two different mechanisms and indicated a sustained attack rather than a single act.The court heard that after the attack, Ngaba delayed seeking help and went to a shop to buy lottery tickets before taking the seriously injured child to hospital by taxi.As a result of the attack, Eliza was placed in foster care in 2021 after Ngaba was jailed for causing grievous bodily harm. Despite living with severe disability, the child was cared for by foster parents Laura and Gary Haynes until his death.Sentencing comments praised the couple for providing Eliza with a stable and loving home. The judge described them as “remarkable” and said they had brought happiness and security to the young girl’s life.In a statement released through West Mercia Police, Eliza’s foster family said: “Our time with Eliza was cut short and our hearts are broken. We are blessed to have Eliza as our family. We love him very much and miss him every day.”Detective Chief Inspector Lee Holehouse described the case as “absolutely heartbreaking” and said Eliza would be living with the consequences of the violence inflicted on her for the rest of her life.He said, “The life sentence given to Ngaba reflects not only the gravity of the harm caused to Eliza, but also that her childhood was so cruelly taken away by the man who was meant to love and cherish her.”Ngaba received a life sentence with the minimum term reduced by time already served for the original assault conviction.
