What is Emma Simmond's connection to the body of the infant discovered near the location she once lived?

Emma is a woman who struggles under the weight of a secret. Although her husband Paul thinks that she has some mental illness that causes her to become anxious and withdrawn, Emma acknowledges that the real cause of her problems are the sins in her past. She is deeply troubled when she reads a newspaper article about the body of a infant that was unearthed in the street where she used to live. She is eager to hear of new developments in the investigation and is waiting for the day when the police will show up at her door to take her away.
