An Adelaide man has been charged with the murder of a woman at a home in the city's southwest.
Louise Hughes, 51, was found unresponsive at the property on Tuesday morning and despite efforts to revive her was pronounced dead at the scene.
South Australia Police said a 33-year-old man was arrested and later charged with murder and breach of bail.
He was refused police bail and will appear in Adelaide Magistrates Court on Wednesday.
Detective Chief Inspector Michael Fisher said a post-mortem examination would determine how Ms Hughes died.
Police believed she and her alleged killer were acquaintances but were not in a relationship.
