A devoted married couple were found dead at their home in Wakefield after an apparent suicide pact.
Jehovah's witnesses are understood to have alerted police after noticing a strong smell coming from the couple's home in Milton Crescent, Lupset, on Tuesday.
Officers broke through the back door and discovered the bodies of Diane Hardcastle, in her 40s, and her husband Derek, aged in his 50s.
Police say there are no suspicious circumstances and are believed to be investigating the possibility the couple deliberately overdosed on unknown tablets.
It is unclear how long the couple had been dead before they were discovered.
Neighbours Bernard and Margaret Stringer, said Mr Hardcastle suffered from kidney problems and had been undergoing dialysis treatment for a number of years.
Mrs Stringer, 71, said: "They were friendly enough and would pass the time of day. Everybody is upset."
Neighbour Kathleen Cotton, 78, said: "They were always together, It's a shock when it's a couple like that with no age to them."
Her husband Walter Cotton said: "They were devoted, you never saw one without the other."
A police spokeswoman said: "We are not treating the deaths as suspicious."
Post mortem examinations have been carried out and inquests are due to be opened in Wakefield
