A teenage nanny was convicted of involuntary manslaughter of a Boston baby in her care following his death.
Louise Woodward, from Elton in Cheshire, was at the centre of a trial in 1997 which shocked the world and fell under the eyes of a global audience.
The au pair was just 19-years-old when she was convicted of the involuntary manslaughter of eight-month-old Matthew Eappen while caring for him in his home in Newton, Massachusetts.

Five days after being admitted to Children's Hospital in Boston, baby Matthew fell into a coma and tragically died on February 9, 1997 from a fractured skull and a subdural haematoma - a serious condition where blood collects between the skull and the surface of the brain.
The eight-month-old was also found to have a fractured wrist, which was an unnoticed and unexplained injury from a month earlier.
A doctor at the hospital also found retinal haemorrhages when examining Matthew, which is a judged characteristic of shaken-baby syndrome.
And after Woodward was reprimanded by authorities, she admitted to playing "a little roughly" with Matthew days before his death.
The tragic case saw Woodward in an all-or-nothing trial, where no charge lesser than second degree murder would be considered.
The polarising trial saw the jury deliver a guilty verdict, after being presented with evidence of symptoms synonymous with Shaken Baby Syndrome.
Justice protest rallies followed in both the UK and US, on separate sides of the argument.
A grand jury later convicted her of a first-degree murder charge and Woodward was sentenced to 15 years in a maximum-security prison.
However, after her defence maintained that Matthew’s injuries were weeks old, Louise’s sentence was reduced to involuntary manslaughter and she was released after serving 279 days in prison.
Woodward always insisted she had only shaken Matthew lightly to revive him after he fell ill.
She was allowed to return to Britain and went to university to study law.
Woodward began her career in law in Manchester, however decided to change career paths to become a dance teacher.
Woodward moved to Shropshire after she married a truck hire company boss - and has since become a mother.
Now, a new ITV documentary focusing on the trial of Woodward is set to air tonight.
The programme marks 25 years since the high profile US court case which shook both sides of the Atlantic.
In its description of the show, ITV said: "At the time the highest profile court case in the US featuring a British defendant, the trial was played out on television screens across both sides of the Atlantic.
"This programme, marking 25 years since the 1997 trial, features access to many of the key figures closest to the case, aiming to illuminate each key step of the trial and its aftermath."
*The Trial of Louise Woodward airs Thursday at 9pm on ITV and ITVHub
