A mother and her disabled daughter found dead in a house had refused help from social workers, a council has said.
Stephania Wolf, 67, and her 29-year-old daughter Sam Wolf were discovered in Marford Road, Wheathampstead, Hertfordshire, on Saturday.
Tests suggested the pair did not sustain any external injuries.
Hertfordshire County Council said they were known to adult care services but had refused the offer of help.
Neighbours said the mother had once pinned a sheet on the tiled roof of her home with the word "help" in red letters.
It remained on the house for a number of days, before being removed.
The council said the two women had undergone a care assessment in 1998 and were provided with equipment for the house.
Social services had final contact with the family in March 2006, when the daughter finished her further education, it said.
The council said it was agreed at that meeting that the family would maintain contact through their GP.
The council is now looking into the case.
Police said full results of post-mortem examinations would take several weeks but the women had not sustained any external injuries or were victims of violence prior to their death.
Forensic tests to establish the cause of both deaths are ongoing, a police spokeswoman said.
"Detectives believe the circumstances surrounding the deaths are not suspicious and are not looking for anyone else," she added.
