Thursday and Friday saw the last two days of evidence given by David Heiss, the German man accused of murdering fellow Advance Wars gamer Matthew Pyke in Nottingham, England.
In those last two days of evidence, Heiss was confronted with accusations that Pyke had cowered as his assailant stabbed him 86 times.
Heiss denied suggestions by the prosecution that he had chased Pyke down a corridor.
However, when asked by the prosecutor why he had run after Pyke, Heiss replied: "We had crossed the line that nobody should cross and I was so afraid he would call the police and tell them I had assaulted him."
Heiss also claimed that after Pyke's death, he had been very distressed on his flight home to Germany.
He said: "While I was on the plane, I had a really hard time not to burst into tears. I would have turned to the person on my left and said, 'You might not believe me. I have just done something incredibly terrible.'"
Heiss admitted Friday that he had changed his clothes and washed his hands after Pyke's death. He described himself as "very panicky."
To which the prosecutor, Shaun Smith, asked: "So panicky you are able to take a pair of Matthew's shoes?"
Heiss' reply: "Well, they were lying on the floor in the living room."
The prosecutor, summing up the case, said: "It was an attack born out of obsession and hatred in equal measure. Obsession for Joanna Witton, who was Matthew's girlfriend, and hatred for Matthew, because Matthew was Joanna Witton's boyfriend and because of things that happened over the Internet."
Whitton and Pyke had blocked Heiss from the online forum Warcentral.com.
The prosecutor spoke to the jurors about the last minutes of Pyke's life: "You know he tried to crawl away. You know that with his dying breath he tried to write David Heiss' name on the computer tower. You know all that, but to imagine what it was like is impossible."
Both prosecution and defense have made their closing arguments and the jury is now considering the evidence.
