JURORS, who heard how a woman watched her former boyfriend being stabbed to death, were expected to be sent out to consider their verdict today.
James Samuels, 22, of Towngate, Newsome, has denied murdering Mark Fisher in the early hours of September 22 last year.
Mr Fisher, 18, of Chickenley, Dewsbury, died after being stabbed nine times at the home of his ex-girlfriend Kristienne Wood, 21, in Woodburn Avenue, Earlsheaton.
Wood has denied perverting the course of justice by hiding the knife behind a greenhouse.
The jury, sitting at Leeds Crown Court, heard how Mr Fisher found Samuels and Wood together at her home, broke in, and attacked them in a rage.
Prosecutor Andrew Campbell QC, summing up yesterday, said Samuels had lied about events in the house.
Samuels told the court he had picked up a knife to defend himself against Mr Fisher, a burly 19st Rugby League player. But Mr Campbell said of Samuels' actions: "He knew what he was doing and that was, he was going over the top, against albeit a heavily-built young man, an unarmed young man."
Defending Samuels, Graham Hyland QC said he had feared for his life and acted in self-defence: "Mark Fisher was consumed and overwhelmed by jealous rage to such an extent that he lost all control of his senses.
"He was a man determined upon doing physical harm to both Kristienne Wood, but principally James Samuels."
He said Samuels had found himself in a desperate situation.
Judge James Stewart said both defendants were of good character. He said Mr Fisher was emotionally vulnerable and still loved Wood: "It was Mark Fisher on his own in the house. He took no weapon to the house."
But Mr Stewart said Wood had acted instinctively and without thought when she hid the knife.
The case continues.
