Who is Lindy from Ghost Girl: The True Story of a Child in Peril and the Teacher Who Saved Her and what is their importance?

Lindy is the policewoman from Falls River that the social worker calls in to handle Jadie's case. Although Lindy repeatedly questions Jadie about the abuse, Jadie refuses to talk to Lindy. Lindy tells Torey that without Jadie giving her own testimony of what has happened to her, there is very little chance that the girls will be taken from their parents permanently. Jadie finally agrees to talk to Lindy as long as she can lock them into the cloakroom together. After Lindy hears what Jadie has to say, she tells Torey that she has never heard such a gruesome story during all of her years on the police force. Lindy promises Jadie that later that day the social services workers will take her to a permanent foster home.
