Hill stabbed Mr. Riddiough-Allen outside Eclipse Nightclub after the venue closed, also injuring four others with a hidden serrated hunting knife.

Mr. Riddiough-Allen tried to intervene and prevent further harm but died from a wound to his abdomen.

At the sentencing in Truro Crown Court, Mrs. Justice Cutts honored Mr. Riddiough-Allen as a man of exceptional qualities and attributed his death and the injuries to Hill's decision to carry a knife.

Tia Taylor, 22, from Bodmin, was sentenced to three years in prison for manslaughter and perverting the course of justice.

Her co-accused, Chelsea Powell, 22, also from Bodmin, received 15 months for perverting the course of justice.

The judge noted that Hill, who carried a weapon during a brawl, showed no remorse and described the incident as a "paradigm case" of knife violence.

The victim's sister, Becky Dustan, read a victim impact statement expressing the profound impact of Mr. Riddiough-Allen's death.

Taylor will be eligible for parole after 18 months, while Powell was released immediately due to time served on remand.

The speaker expressed that the death of Michael Riddiough-Allen was devastating for everyone involved, and his family would never be the same.

She described how his attempt to protect others from a man with a knife resulted in his own death, leaving him humiliated and lying on the ground.

Detective Inspector Ilona Rosson from Devon and Cornwall Police stated that Riddiough-Allen tried to protect those around him and disarmed a man, but unfortunately lost his life in the process.
