Christopher Brian Newlove has told his murder trial he was fast asleep when his best friend of 10 years was killed in the living room of his inner-Brisbane unit.

Newlove gave evidence on Friday where he denied any involvement in the death of Paul Heron in Highgate Hill on March 6, 2015.

His mate's blood-stained body was found on his kitchen floor in the early hours of that morning after Newlove called triple-zero.

The 42-year-old died as a result of a slash to his neck with a machete, but he was also hit in the head multiple times with a brick and had his genitals burnt.

The court heard Newlove had taken 20 tablets of valium and drunk three-quarters of a bottle of vodka in the hours leading up to the alleged incident.

He said he woke up to the sound of the fire alarm going off.

"Then I saw Paulie on the floor in a pool of blood," he said.

Newlove admitted he lied to police over the course of the night when he claimed he saw two men break into his home and murder his friend.

"I just weaved a web for myself. I started lying and I just got stuck with it," he said.

He maintained he was not responsible for Mr Heron's murder, but crown prosecutor David Meredith disagreed.

"Mr Newlove, you killed Paul Heron for whatever reason and then tried to hide it," he said.

"No," Newlove replied.

He also denied seeing the machete when he claimed he found Mr Heron's body but later corrected himself to say he may have after he was heard describing his friend's injuries in a triple-zero call.

"He's been stabbed and burned and macheted," he told the operator.

Newlove denied he told police about the brick, but not the machete because it was his and would implicate him more.

Defence barrister Kim Bryson put to the jury in her closing that her client was "very intoxicated" by drugs and alcohol and may not have been capable of forming an intention to kill Mr Heron.

But she left it open for the jurors to find Newlove guilty of the lesser charge of manslaughter despite his assertions he played no role.

"The only rational explanation for Paul's death is Chris Newlove's intoxication," she said.

Mr Meredith said just because someone was intoxicated didn't mean they couldn't murder someone.

"If you can form a lie you can form an intent to kill," he said.

"I'd suggest you have no choice if you're considering this logically, but to convict him of murder."

Justice Peter Applegarth will deliver his summation on Monday before the jury retires to consider its verdict.
