A court has heard how a man from County Durham tried to kill his parents for a £230,000 inheritance by allegedly driving them into a canal.
Stephen Seddon staged the "accident" by driving into a canal with his parents and nephew all aboard the BMW car on March 20th of last year, the court heard.
Seddon hired a BMW and drove from his home in the North East on the pretext of taking his parents and nephew out for a meal.
He later told police a brick in the road may have caused him to swerve off the road and into the water.
Ruth Carroll told the court she was driving along Canal Road in Timperley, south Manchester, when she saw the vehicle on the night of the alleged attempted murder.
Seddon denies two counts of murder and two counts of attempted murder.
"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."
A County Durham man accused of killing his parents has denied that he considered killing his "disabled" nephew, a court has heard.
A man accused of killing his parents for his inheritance has said he was on a drugs run for crime gangs on the day of their murders.
