The woman was discovered in her bed, naked from the waist down and flanking a sex toy in Aveiro, a town just south of Porto, Portugal.
There were also severe injuries to the woman’s genitals that authorities believed were caused by the sex toy discovered next to her body, Jornal de Noticias, a Portuguese newspaper reported.
“I noticed only two small bruises on her face, but there was blood on the sheets and a picture of her husband resting on her chest,” Ana Martins, the neighbor who discovered her, told the newspaper.
Martins added that the woman was a sailor’s widow, had an affinity for cracking jokes with men and was very active despite her age.
The next-door neighbor — who happens to be a married father of two — was collared after officials discovered his DNA in the semen at the scene, the Mirror reported.
He was later released on bail and the judge notified him that the woman died from asphyxia based on autopsy results. The death is being considered an accident and police said there was no sign of forced entry.
