Juvenile
A drug raid leads to the grim discovery of a woman who has been raped and murdered. A very extensive pot-growing operation is found in her house and the "merchandise" is untouched. Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) find out from the Medical Examiner that the victim had ovarian cancer and was undergoing chemotherapy. They deduce that instead of being a street drug dealer, the victim was growing the pot to use for her own medicinal purposes, but that doesn't answer the question of who killed her. There is a break when M.E. Warner (Tamara Tunie) finds Benson and Stabler having lunch. They analyzed the vomit at the scene and it matched the NYC schools' middle school lunch menu that day, and with no sperm found on the victim, they presume their perpetrator is an adolescent.
