A post-mortem examination found Sara had suffered injuries including "probable human bite marks", an iron burn and scalding from hot water before she died on 8 August last year.
Next to Sara's body, which was found by police in a bunkbed, was a note in her father's handwriting, which read: "Whoever see this note, it's me Urfan Sharif who killed my daughter by beating."

Jurors were initially told that Sharif's case was that Batool was responsible for Sara's death, and he made a false confession in a note and a subsequent phone call to protect his wife.
However, Sharif went on to accept "full responsibility" for Sara's death under cross-examination.
Sara's mother, Olga Domin, has paid tribute to her daughter, stating: "Sara's smile could brighten up the darkest room."
She said Sara had beautiful brown eyes, an angelic voice and a unique character.
"She will always be in our hearts, her laughter will bring warmth to our lives," she said.
"We miss Sara very much. Love you, princess."
Sharif married Ms Domin in 2009 but separated in 2015, with accusations of abuse made against each other in a custody battle.
In 2019, Sara was living with her mother when Guildford's family court awarded custody to Sharif, who had by then divorced Sara's mother and married Batool.
