The law actually requires DCF to go in and save her:
"If it appears that the vulnerable adult lacks the capacity to consent to emergency protective services and that the vulnerable adult, from the personal observations of the representative of the department and specified medical personnel or law enforcement officers, is likely to incur a risk of death or serious physical injury if such person is not immediately removed from the premises, then the representative of the department shall transport or arrange for the transportation of the vulnerable adult to an appropriate medical or protective services facility in order to provide emergency protective services. Law enforcement personnel have a duty to transport when medical transportation is not available or needed and the vulnerable adult presents a threat of injury to self or others."
The law is here in black and white: The police must save Terri.
