A homeless man who toured the UK in his van took his own life, an inquest heard.
Peter Blissett, 69, was living in his van when he was found unsteady on his feet by staff in the car park of Tesco fuel station in Clevedon.
Police had arrived and sat Mr Blissett, of no fixed abode, in the back of their car.
When paramedics arrived, he said he had made a 'staggered suicide attempt'.

The inquest at Avon Coroners Court heard Mr Blissett had a swollen tongue and was jaundiced. An echocardiogram (ECG) of his heart also showed some abnormalities.
Paramedic Hannah Thomas told the inquest: "We advised the patient he should go to hospital for further treatment for further investigations for his jaundice and swollen tongue."
Mr Blissett, who also had a history of alcohol abuse, was taken to Weston General Hospital by ambulance.
He was transferred to the hospital's intensive care unit where his condition deteriorated and he suffered a gastro intestinal haemmorage and a cardiac arrest and died at 7.30am on January 11.

The inquest heard Mr Blissett had taken medication in the three days before his death.
The cause of death was given as gastro intestinal haemmorage due to paracetemol intoxication and deranged liver function.
Assistant coroner for Avon Terence Moore said: "It appears that Mr Blissett had taken a massive overdose during the two to three days previous to his admission to hospital as a staggered suicide attempt."
Mr Moore recorded a conclusion of suicide.

Most people who are thinking of taking their own life have shown warning signs beforehand.
These can include becoming depressed, showing sudden changes in behaviour, talking about wanting to die and feelings of hopelessness.
These feelings do improve and can be treated.
