A man sentenced to life for killing his father had his sentence reduced by the Court of Appeal.

Tyshaun Brown, 28, plead guilty last year to the killing of his father and was convicted of manslaughter on the basis of diminished responsibility.

Puisne Judge Shade Subair-Williams gave Brown a life sentence. He was required to serve at least 12 years before becoming eligible for parole.

However, the Court of Appeal has slashed his sentence to 20 years behind bars, of which he must serve at least one third before becoming eligible for parole.

The Appeal Panel further ordered that Brown must participate in treatment programmes while incarcerated and continue his treatment on an ongoing basis upon release.

A written judgment with the reason for the decision is expected to be released soon.

The court had heard Amon Brown, 52, died on July 8, 2020 after an argument with his son on St Mary’s Road, Cedar Hill, Warwick.

The court heard that he had driven his son to the house of his mother, Margaret Moore, after he picked him up from a cricket game in Somerset.

The two argued over the defendant’s former wife, and Brown phoned his sister, Shauntorri Franks, at 11.30pm and shouted: “I’m going to kill Daddy.”

The summary of evidence said Brown hit his father and knocked him off the porch, punched him several times, then went inside and told Ms Moore that he was going to “get a knife to kill Amon because he deserved to die”.

Brown handed the phone to his terrified mother, who phoned 911 as her son grabbed a knife and stabbed his father several times.

Brown chased his father, threatened a neighbour who tried to intervene and knifed Mr Brown, including a wound to the heart.

He later told police: “I killed my own daddy, bro, I did it — I deserve life”.

At his sentencing last April, Mrs Justice Subair Williams said Brown showed “the ferocity of an enraged wild dog” in the attack, stabbing his father 26 times.

She added: “Instead of dying as an old man in the loving company and care of his family, Amon Brown suffered a cruel and prolonged fatal attack, knowing that it was his own son that did this to him.”

The judge said that Brown may still suffer from the trauma of seeing his sister die in a road crash, but that he had put himself in a position that allowed the brutal attack to take place.

Mrs Justice Subair Williams said Brown was aware that he needed treatment and that alcohol contributed to his outbursts of rage, but that he had still opted to drink on the day of the attack on his father.

She highlighted that Brown’s mental health issues were discussed during a 2019 case in which he was sentenced to three years’ probation for violently resisting arrest.

She said: “The accused knew all too well on July 8, 2020, that he was filled with a long-lasting and high dose of anger and hurt inside of him, and he knew that his excessive alcohol consumption would inevitably lure him into an uncontrolled and violent disposition.”
