Sunny's observation that there have been several dead prostitutes pulled from the water in recent months prompts Da Vinci to have a number of similar deaths re-examined. Following up on these cases, Det Leary questions a local cafe owner - Charlie Josephs - who knew the most recent victim. Joseph's MO is to get the girls to drink so much alcohol that they die of alcohol poisoning, have sex with them and then dump them into the water. In a separate case, an infant is found to have died of a heroin overdose. After an interview with the child's nanny and a search of the home, the father admits to storing his drugs in a talcum powder container that the nanny had used earlier on the infant.
