A man stabbed to death by a friend in a Sydney street must have been a blind zombie with no regard for self-preservation and an immunity to pain for his killer's story to be true, a jury has been told.
Peni "Ben" Apikotoa, 34, bled to death on the doorstep of a St Clair home in August 2018 after Nathan Chatimba plunged a knife seven centimetres into his shoulder and severed a major artery.
Mr Apikotoa had come to the home of Chatimba's ex-partner Cassie Sanders after the accused angrily confronted him on the phone about his suspicions the pair were seeing each other.
Chatimba, now 33, has pleaded not guilty to murder, claiming self-defence.
In his closing address to the Supreme Court jury, crown prosecutor Gareth Christofi said Chatimba had lied to police in the hours after the attack and is lying still.
The scaffolder claims Mr Apikotoa punched him in the face while he was holding his child, sparking the incident.
He then picked up a knife that was on a pile of rubbish near the house and brandished it obviously to make his friend stop attacking him, he says.
But Mr Apikotoa wouldn't stop coming at him and he stabbed him six times in self-defence.
"It does sound like tall story - does it not?" Mr Christofi said.
"There just happened to be a knife right there... how fortunate, how convenient."
Further, it is extremely unlikely the victim would have punched Chatimba while he was holding a child, the Crown contended, or that it would have taken six stab wounds to stop him advancing.
He would have to be blind to have missed the knife, and a "zombie" without regard for self-preservation or pain to not let the initial stabs stop him.
"It is almost cartoonish," Mr Christofi said.
On top of his "most unlikely" story, Chatimba had a record of lying to police, Mr Christofi said.
Among the series of lies, he said, were three different stories Chatimba had come up with about where the knife came from.
He told police the victim had brandished it first, then said he found it in the rubbish, and was later caught out in a covert recording admitting to his partner that he had brought it with him from inside his ex-partner's house.
Chatimba also claims he fled the scene because he was concerned Mr Apikotoa would return with his friends and attack him, despite his extensive injuries.
"There are so many things wrong with that story it is difficult to know where to begin," Mr Christofi said.
Furthermore, Chatimba was "caught red-handed" charging at the victim with a knife while he had his hands up in surrender, the jury was told.
From the driveway next door, neighbour Shane Stonestreet had earlier told the court he had a clear view of Chatimba charging at a man in a fluoro top.
"While the accused was charging, the man in the fluoro was back-pedalling... with his hands up," Mr Christofi said.
The streetlight had illuminated a 20cm knife in Chatimba's hand, and Mr Stonestreet then saw him swing down at the other man.
The pattern of blood found in the street after the attack is consistent with Mr Stonestreet's version of events, Mr Christofi said.
The severity, location and number of stab wounds support it too.
"Low and behold, three of these stab wounds were very nasty wounds to both of the deceased's forearms and to the back of his right wrist," he said.
"It is worth noting that there were no injuries whatsoever on the accused."
Chatimba was angry and jealous, Mr Christofi says, and the attack was not self-defence at all.
The trial continues on Thursday, when Chatimba's defence yet to present closing arguments to the jury.
