Ariik Mayot killed Lindsay Ede in one-punch attack in 2015 Unlawful striking causing death carries a maximum life sentence

Unlawful striking causing death carries a maximum life sentence Ede's family "very disappointed" in Mayot's six-year sentence

A remorseful Ariik Mayot, 20, pleaded guilty in December to hitting 54-year-old grandfather Lindsay Ede on a Goodna Street in June 2015.

Mayot was the first person in Queensland to be charged with unlawful striking causing death, which carries a maximum penalty of life in prison.

"I have to live with the fact I took someone's life. I am so sorry, I am not asking for forgiveness," Mayot said in a statement read by Chief Justice Catherine Holmes.

"What I did, it never gets out of my head. I will never be able to make up for it.

"He didn't deserve to die — I felt sick reading the victim impact statements from the family."

'To my family you are a murderer'

The court heard Mayot, who is from a large Sudanese family, experienced racism and bullying when he was younger.

When Justice Holmes handed down the sentence she said she accepted Mayot's assertion that Mr Ede may have called him a "black bastard" before the attack.

He was heading to the police station to report for breach of bail when he crossed paths with Mr Ede.

Mr Ede was on his way to his brother's home in Goodna, which was less than a kilometre away.

His brother Terry Bishop said the victim had a gentle soul.

"How cruel are you to even have thrown a punch at my brother - what did he ever do to you?" he said in his victim impact statement.

"To my family you are a murderer.

"He loved walking as it was his only time out from caring for his frail partner."

Family and friends of Mr Ede walked into the Supreme Court in Brisbane together on Monday, wearing "one punch kills" T-shirts.

Speaking outside court, Mr Bishop said he was "very disappointed" with the sentence.

"[It's a] very sad day to be honest — I think my brother's life was worth more than that," he said.

"At the end of the day it didn't really matter how much he got sentenced, because it was never going to be enough, but at least 15 [years] would've been nice, even 10 [years], but it'll never bring back Lindsay."

Mr Ede's partner of 17 years, Gloria Stephens, said he was "one of the best".

"There is a hole in my life that can never now be filled, I am incomplete," she said in a victim impact statement read in court.

Mr Ede's daughter Kylie Beckett described him as "a loving, caring, kind hearted man."

"I would give anything for him to be with us again ... I miss him greatly."

Mayot will serve at least five years behind bars.

He has already served almost two years so will be eligible for parole in 2020.
