The death of a woman at a village shop is being treated as murder, police have said.
A man remains in police custody as inquiries into the death of the woman continue.
The investigation was launched after police were called to a property next to the Royal Oak Stores in Crookes Lane, Kewstoke, near Weston-super-Mare.
Police said the victim, named locally as Julie Tottle, died from head injuries following a "sustained assault".
A man, named locally as the woman's husband Stephen Hotson, remains in police custody following the incident on Tuesday.
Detectives said he was hurt after appearing to fall from an upstairs window at the property. Mr Hotson was taken by air ambulance to Frenchay Hospital in Bristol, where he is in a stable condition with life-changing injuries. He has since been arrested on suspicion of murder.
Detective Chief Inspector Phil Jones, who is leading the investigation, said: "We are treating this as a murder inquiry. A man has been arrested. At this stage we are not looking for anyone else."
Mr Jones said: "Although I am keeping an open mind, I believe this is an isolated incident but would urge anyone in Kewstoke to come forward with information.
"I would particularly like to hear from anyone who can help us piece together what happened in the hours leading up to the discovery of the body on Tuesday."
A man in his 40s, who was arrested at the scene, was later released without charge.
