A young mother calmly staged the death of her baby on a London bus in a bid to cover up the horrific abuse and murder of the child at home, a court has heard. Rosalin Baker, 25, was given the “thumbs up” by her 52-year-old boyfriend, Jeffrey Wiltshire, as she boarded the number 25 service in Stratford, holding the body of their 16-week-old daughter, Imani, jurors were told.

She went on to act out a “nightmare” charade, asking passengers for help and saying her baby had just fallen ill. But Imani, who was born prematurely, was already dead after being subjected to at least three severe attacks and flung on the floor. Imani was pronounced dead in hospital and her parents went on to give a false account of what happened to police. The baby had a broken wrist from her arm being “pulled or twisted” and at least 40 rib fractures from her chest being squeezed as she was shaken; she also had a fractured skull and brain injury “as the result of being thrown against the floor or an upright surface” which led to her death.

Prosecutor Duncan Atkinson QC told jurors: “During the course of the bus journey, Baker suddenly sought help from her fellow passengers for a problem that she said she had just identified with her daughter. Those members of the public, presented with the nightmare of an infant who was not breathing, did all they could to help. They were panicking and distressed. In contrast, Baker was noted to be cold and calm.” The couple deny murder and the case continues.
