House Calls (S13E21)

A young model is shopping when the security cameras pick her up shoplifting. When the store manager attempts to confront her in the dressing room there's no response, because she is lying there dead. The victim, Nadia Parkova, is an aspiring model. Found by her body is an empty syringe with traces of Demerol. Cause of death was cardiac arrest and it was a lethal combination of asthma medicine and the Demerol that did her in. But her body showed serious signs of abuse and internal injuries. The Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) think perhaps her boyfriend or father was beating her, but her younger sister Lena (Alexis Dziena) says that's not true, she's accident-prone and fell down the stairs. (iTunes)
