Mr and Mrs Andrews’ daughters Sally and Lucie read out a family statement outside the coroner’s court.
They described their father as a “true Yorkshireman” who loved ballroom dancing, while their mother was a “people person” who made lunches for elderly neighbours.
Together they were called “a team of enviable strength”.
The sisters found their parents fatally injured at their home.
Sally told the court there was “some comfort that we, including Duncan, were there together for one final time”.
“They would have been absolutely devastated that day,” she added.
Speaking on a video link from a secure hospital, James Duncan Andrews said: “I loved my parents right to the end. I wish this had never happened.”
He thanked his sisters for their support during the inquest.
“We are deeply sorry for the tragic loss of Bryan and Mary Andrews in November 2022, and our heartfelt sympathies remain with their family,” Ms Crimlisk, from the NHS trust, said.
“All those involved with Duncan’s care have taken immediate steps to learn from this tragedy. We have already made a number of changes and we will continue to make improvements to address the concerns highlighted through the inquest process.”
The coroner recorded a conclusion that Mr and Mrs Andrews were unlawfully killed.
