Lloyd Davies, 28, a car salesman, was shot in the heart when he argued with a man in a pub over a car parked outside the showroom where he worked. Barry Crane, 34, shot him in the pub at Stoke Newington, north London, David Paget, for the prosecution, said. The court was told Mr Crane may have shouted racial abuse at Mr Davies, who took out a knife. Mr Crane produced the gun and Mr Davies lunged at him with the knife, cutting him on the chin and thumb, Mr Paget said. Two shots were fired. Mr Crane, a motor trader, from Hampshire, denies murder. The trial continues.
