He said the boy "will not be giving evidence" as he "does not support the prosecution", adding: "What we have are the observations of some of those adults who witnessed Lindy Leah interact with [the boy] and who will say that her behaviour was often highly inappropriate.
Lindy Leah, 44, is on trial at Liverpool Crown Court accused of inciting a child to engage in sexual activity.
The married mum-of-two was also said to have "fallen in love with" the teen, and sent him what were described as "highly inappropriate" messages, reports the Liverpool Echo.
A care worker who allegedly had a sexual relationship with a boy at a children's home encouraged him to go missing over WhatsApp, a trial has heard.
Concerns over Leah's behaviour led to her being spoken to by the police in June last year, though she "denied any improper behaviour", the court heard.
