Summary Eleven year-old Nelson Kauf is found dead, hanging off the roller coaster. He is known to police as he continually called them regarding domestic problems at home. These were all deemed by the police to be nuisance calls. He was also cited by others for mischief. Da Vinci learns that Nelson was on antidepressants, the prescribing doctor - Dr. Ludlow - who has a history of over-prescription. Da Vinci is about to sign off that Nelson's medication dosage and his death have no relationship, until he learns more about the earlier death of Nelson's father, also with a history of depression and suicide attempts and whose doctor was also Dr. Ludlow. Meanwhile, Kurtz is pressuring Kosmo for results from the surveillance on Alex and Sarah regarding the body found under the concrete floor in one of Alex's houses. Kosmo turns up the heat on both Alex and Sarah. Kosmo is playing both husband and wife off each other, a tactic she openly plays to Sarah. As such, Sarah is feeling backed into a corner, and she turns to Danny for advice. The tactic pays off. With the investigation into the tubal ligations of the young aboriginal women, Patricia decides to question the operating doctor, Dr. Wyman, but she is too late to ever get any useful information from the doctor.
