Sarah Walker had previously admitted perverting the course of justice by sending messages from Bernadette’s phone and providing false information to police, without knowing she was dead and with the intention to cover up the sexual allegations against Scott.
However, today she was also found guilty of two alternative charges of perverting the course of justice, which were identical to the charges she admitted - but with the knowledge that Bernadette was dead.
Sarah Walker admitted two counts of perverting the course of justice by sending messages from Bernadette’s phone after she disappeared and by providing false information to the police relating to her disappearance.
Jurors at Cambridge Crown Court found her guilty on both counts by majority verdicts.
Earlier Scott Walker, the man who Bernadette called father, was found guilty of murdering her after she claimed that he had sexually abused her “over a number of years”.
Bernadette, 17, was last seen alive on July 18 last year when 51-year-old Scott Walker, who was not her biological father, collected her from his parents’ house in Peterborough, Cambridge Crown Court heard.
Sarah Walker did not give evidence.
A sentencing date for the pair, of Century Square, Millfield, has been set for September 10.
