"According to the contemporary newspaper reports of the day, Joseph and four other men were traveling in a car near Passingford Bridge which is near Stapleford Abbotts, Abridge in Essex when they were ordered to stop by a sentry but failed to do so. The car was fired upon and Joseph and another man Albert Turner were seriously injured. They were taken to Oldchurch Hospital where Joseph died of his wounds. An inquest revealed that Joseph had died of "heart failure, shock and haemorrhage caused by wounds to the back" and a verdict of Justifiable Homicide was recorded."
"He was accepted as a Civilian War Casualty by the Commonwealth War Graves Commission on the 3rd June 2015"
