Seddon murders: Son 'stood on sinking car'
A man was seen standing on top of a car which he had allegedly driven into a Manchester canal with his parents inside, a court has heard.
Stephen Seddon staged the "accident" by driving into the Bridgewater Canal in Timperley last March.
Witness Elliot Fox said he shouted at Mr Seddon to get off the car as he was making it sink.
The father-of-three, from County Durham, denies two counts of murder and two counts of attempted murder.
Manchester Crown Court heard Mr Seddon's parents Robert Seddon, 68, and Patricia, 65, survived the crash along with his nephew, Daniel, 27, who was also in the hired BMW car when the incident took place.
It is alleged Mr Seddon, 46, deliberately drove into the canal in an attempt to kill his parents as he was desperate to inherit their money.
The jury was told he played the hero after the incident but went on to shoot his parents dead at their home in Sale, Greater Manchester, a few months later.
The couple were found shot dead at close range with a sawn-off shotgun at the house on 4 July last year.
The court heard on 20 March, Mr Seddon drove from his home in the North East on the pretext of taking his parents and nephew, who has learning difficulties, out for a belated Mother's Day meal.
He claims he hit a brick in the road and the car veered off the road.
Ruth Carroll told the court she was driving along Canal Road in Timperley at about 20:00 GMT on a dark, cold but dry night when she noticed headlights of a car being driven fast coming towards her "all of a sudden."
She said: "At the time I thought it might be joyriders - just the speed.
"The lights sort of went off to my left and I saw the side of the vehicle, then it seemed to go up and it went into the canal."
She pulled up and called emergency services before getting out of her car.
"I saw some people standing on the canal bank," she said.
'Please help me'
"There was the car and then I saw somebody sat on top of the car who appeared to be kicking backwards at the car, shouting, 'Help me, please help me.'"
She said she saw an older man get out of the canal, but did not see a brick in the road or any kind of obstruction.
Elliot Fox lived in the Bridge Apartments overlooking the canal and saw the car in the water from his balcony.
He said he saw Mr Seddon in the water trying to break the windows of the car, before he climbed up on top of the vehicle to kick back against the windows with his heels.
Mr Fox said he shouted at him to get off the car as he was making it sink.
Mr Seddon senior and Daniel managed to get out of the car, but Mrs Seddon had to be rescued by firefighters.
The trial was adjourned until Monday.
