A judge said yesterday that a man who killed his father in a frenzied knife attack acted with the aggression of a “wild dog”.

Puisne Judge Shade Subair Williams was speaking as she sentenced Tyshaun Brown to life in prison for manslaughter after he stabbed dad Amon Brown 26 times.

She said: “The deceased, a 52-year-old family man, was beaten to the point of being knocked to the ground and then stabbed mercilessly by the accused, who relentlessly pursued his father as he sought to escape, shirtless and desperately knocking on a neighbouring door for rescue.

“Having already butchered his poor father, who held his hand to his stomach wounds while staggering up a hill, the accused persisted in the attack with the ferocity of an enraged wild dog.”

Mrs Justice Subair Williams 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.”

She said that Brown may still suffer from the trauma of seeing his sister die in a road accident, 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.

“In his defence, I accept that he may not have envisaged the extremities of his violent conduct.”

Mrs Justice Subair Williams warned there was a significant risk that Brown would cause serious harm to others, including members of his own family, and sentenced him to life in prison.

She ordered that Brown should serve at least 12 years before he became eligible for parole.

Some members of Brown’s family appealed for more work by the courts and the authorities to deal with trauma and mental health problems.

Valerie Raynor, the mother of the victim and grandmother of his killer, said: “It was not until he inflicted the 26 stab wounds that took his father’s life that they are saying he had diminished responsibilities.”

She added that, regardless of the sentence, the important thing would be that Brown left prison having dealt with his mental health problems.

Ms Raynor said: “At the end of the day, I have to forgive Tyshaun because he is my grandson. You do not throw your family away.

“My thing is that while he is incarcerated, he should take up anger management and that he gets grief counselling.

“He has put up with his grief for 16 years — how is it that no one saw fit to get this boy some help? Nobody saw fit to get this boy help.”

Brown, 27, pleaded guilty last month to the killing of his father and was convicted of manslaughter on the basis of diminished responsibility.

Amon Brown 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”.

Cindy Clarke, the Director of Public Prosecutions, said Brown’s admission of guilt was the only mitigation.

She asked for a prison term of 25 to 35 years and told the court that the impact on the family had been “much the same as murder”.

Elizabeth Christopher, who appeared for Brown, said that 11 to 15 years was a more appropriate sentence.

Ms Christopher said that the psychiatrist’s report highlighted the “impulsive and unplanned” nature of the attack.

She told the court: “He did it outside his home in front of family members, didn’t flee or try to hide anything and kept saying these strange statements and the ridiculous statement that `he deserved it’.

“Amon Brown did not deserve to die — it’s irrational.”
