From the
BBC.
"A headless body has been found in the grounds of a psychiatric hospital in the Brislington area of Bristol.
The remains were found by staff at Callington Road Hospital, a specialist unit for patients with psychiatric and addiction problems. It is thought the body, and the head found nearby, are those of a man and they had been there for six months. Avon and Wiltshire Mental Health Trust said none of its in-patients had been reported missing in that time.
It is understood the body had been there for about six months and that it may have been recently disturbed by animals. An Avon and Somerset Police spokesman said the death did not appear to be suspicious adding that detectives were studying outpatient records as part of their attempts to identify the remains."
So, a decapitated corpse has been lying about the grounds of a mental hospital for 6 months and the police don't believe there's anything suspicious about it.
As my new-favourite Doctor would say...
