Inquest Into Death In Flooded Car
An inquest will resume today into the death of a man whose car was swept away by fast-flowing water as he drove across a ford.
Jonathan Gammon, 52, from Kingston Lane, Teddington, Middlesex, was trapped in the Toyota Yaris as he attempted to cross the swollen ford at Thornford Road, Headley, Hampshire, on April 30.
The car was swept about 100 yards downstream and became submerged by flood water, according to Hampshire Police, following heavy rain in the area.
Mr Gammon's wife, who was 55 at the time and was understood to have been driving the vehicle, was able to get out.
She was taken to hospital where she was treated for shock.
Mr Gammon, a ''well respected'' Mental Health Tribunal judge, was recovered from the vehicle by fire and rescue crews and later pronounced dead at the scene.
A dog which was in the car also died.
Phillip Sycamore, president of the first tier tribunal health, education and social care chamber, said in a statement released at the time of Mr Gammon's death:
''I am greatly saddened and shocked by the tragic death of my colleague Jonathan Gammon.
''Jonathan, who had tremendous talent, became a full-time judge in 2009 having previously had a distinguished career as both a barrister and a solicitor.
''He was a very well respected and popular colleague.
''Our thoughts are with his wife and family. He will be much missed.''
The inquest in front of North Hampshire Coroner Andrew Bradley will take place at Alton Magistrates' Court.
