Soham accused Ms Maxine Carr angrily denied any suggestions she or Mr Ian Huntley groomed Holly Wells and Jessica Chapman before they disappeared, the Old Bailey heard today.
Ms Carr was questioned by police following her arrest over whether she used her friendship with the girls to help "form a plan".
She denied that she deliberately befriended the 10-year-olds and then left Soham on the weekend that they disappeared in August last year.
The jury at the murder trial heard excerpts from her police interviews after she was arrested on suspicion of murder on August 17th - 13 days after Holly and Jessica disappeared.
In the interviews police asked Ms Carr why Mr Ian Huntley would pick on those two girls who were known to be friends of hers.
The court has already heard that Ms Carr was a former temporary classroom assistant in the girls' class at St Andrews School.
Mr Huntley, who denies murdering the girls, has already admitted removing their dead bodies and taking them in his car to woodland where he dumped them in a ditch and cut off their clothes. The bodies were found in a ditch near Lakenheath, Suffolk about 15 miles from their homes in Soham.
Ms Carr denies assisting an offender and conspiring to pervert the course of justice.
