A man who kept his sister captive in "dungeon"-like conditions for several years inside her Seymour, Connecticut home has been sentenced to 6-and-a-half years in prison.
Arthur Gauvin was responsible for his sister's care and he locked her up to avoid losing her home to the state, police said.
He pleaded guilty in April to abuse and cruelty charges.
Police arrested the 60-year-old Gauvin in April 2014 after receiving an anonymous call from someone who was concerned about the woman's welfare.
When police responded to the home to investigate, they found an extremely thin woman who was disheveled and covered in urine and human feces, police said. She had not bathed for a long time and it appeared she had been malnourished.
Police said the victim was suffering from diabetes and dementia and had been held captive for years.
The single window in her room was boarded up to keep her from escaping and it was covered over with black paint to prevent her from seeing outside, police said.
Gauvin was sentenced on Thursday in Milford Superior Court. A plea agreement called for him to serve between five and 10 years in prison.
