Vulnerable

S4 E3: Residents of a Lower East Side apartment are startled when an intruder breaks in during the middle of the night. It turns out to be "Granny Doe" - an elderly woman who can't remember where she is. Granny has been burned and possibly raped. But she isn't much help when Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) question her due to her Alzheimer's disease, which has left her with severe short-term memory loss. Eventually, the detectives discover her identity by researching past tenants of the apartment building. Their victim is Bess Sherman (Jane Powell), who is in her 80's. According to a woman who previously lived in the apartment, Bess used to sneak into the apartment in the middle of the night when she was a young girl. Apparently, she had a "funny uncle." Bess was living at Jubilee Towers; an upscale assisted living facility for adults, but had recently been released to the custody of her son, Joe Sherman (Jay Thomas).
