A husband in his seventies is on trial for sexual abuse and could face up to 10 years in jail for having sexual intercourse with his wife, who suffered from Alzheimer's disease.
A jury will have to decide whether Donna Lou Rayhons, who died last year, was mentally capable of consenting to sex with her husband, Henry, in a case being closely watched by doctors and dementia charities.
Mr Rayhons (78), a farmer and prominent Iowa state politician, met his wife singing in a church choir after both had been widowed.
They married in 2007; she joined him while he conducted business at the state capitol and they spent their time off beekeeping. A few years into the marriage, Mrs Rayhons was diagnosed with Alzheimer's disease and her condition deteriorated rapidly, but the couple continued to have conjugal relations. Early last year, at the age of 78, she was moved into the Concord Care Center, a nursing home two miles from where she lived with her husband in Garner, Iowa.
In May, her husband was told that the nursing home had concluded that Mrs Rayhons was not able to consent to sex. At the behest of one of her daughters from a previous marriage, who had concerns, Mrs Rayhons was moved from a private room to a shared one on May 23.
