A TEENAGER was stabbed to death after forcing his way into his former girlfriend's home, a jury was told at Leeds Crown Court.
Mark Fisher, 18, of Chickenley, Dewsbury, was stabbed nine times with a kitchen knife during the early hours of September 22 last year.
He died on the driveway of a house in Woodburn Avenue, Earlsheaton, the family home of his ex-girlfriend Kristienne Wood, 21.
Prosecutor Andrew Campbell QC told the jury the stab wounds were inflicted by James Samuels, 22, of Towngate, Newsome, who has been charged with murder.
Wood has been charged with perverting the course of justice by hiding the knife behind a greenhouse.
Both defendants have denied the offences.
Mr Campbell said Mr Fisher, who was a keen rugby league player, had been out with friends in Dewsbury and Batley on September 21.
Mr Fisher left The Spangled Bull pub at Earlsheaton at 1.30am, on September 22 with his friend Patrick Quinn.
Mr Quinn told the court he went to Wood's house at Woodburn Avenue with Mr Fisher to check she was all right while her parents were away.
Mr Quinn said: "I just said to him don't do anything stupid because he will lose her forever. He said: `I'm not going to'."
He said Mr Fisher went to the side door of the house while he waited near a car in the driveway.
Wood and Samuels, who were workmates, were chatting inside.
Mr Fisher knocked on the door calmly at first, but he became angry.
Mr Quinn said: "He got angry. He said, `Open the f***ing door now'."
He banged on the door with both hands and smashed the glass pane.
Wood could be heard calling the police inside the house.
Mr Fisher went around the back of the house,
smashed patio doors and entered the house through the kitchen.
Mr Quinn went to his friend Dominic Cox's house nearby on Walker Street to ask him to help calm Mr Fisher down.
Mr Quinn then got a call from Mr Fisher saying "I have been stabbed in the head and in my back. Get back down here and help me."
Mr Campbell said according to James Samuels, Mr Fisher burst into the kitchen, argued with Kristienne Wood then attacked him in the living room.
Samuels claimed Mr Fisher head-butted Wood then scuffled with him back into the kitchen.
He said Mr Fisher, who weighed 18 stones, pinned him down so he grabbed a knife and stabbed him once in his back, cutting his own hand in the process.
Mr Campbell said Samuels claimed the stabbing was in self-defence.
Samuels originally said he hid the knife in the garden, but later said he gave it to Wood.
Mr Campbell said Wood initially denied all knowledge.
The trial continues.
