The bereaved parents of Alex Innes were facing ‘every parent’s worst nightmare’, the detective who brought his killer to justice said.

DCI Jon Capps of Thames Valley Police’s murder squad described now convicted murderer Greg Muinami as having shown ‘no remorse’ for carrying out the brutal stabbing.

“Alex went out that Saturday evening for what should have an enjoyable and social night out. He had every right to feel safe. He was happy; friends say that Alex was always happy,” the detective said.

“Greg Muinami had armed himself with a knife that night. He intended to use it to resolve what he perceived to be an argument over a pair of trainers and him owing an associated debt of £100.

“Alex tried to resolve things amicably, but Muinami fatally stabbed Alex Innes in a horrific act of violence and has shown to be a coward ever since, giving no account for his actions.”

He added that Mr Innes’ parents, who spent every day in the trial of the four teenager accused of his murder, had shown ‘enormous dignity and strength’.

Mr Capps said: “They are facing every parent’s worst nightmare and have heard and seen all the evidence. Their strength to see justice done for Alex has been humbling.

“Alex’s family have put their trust in our investigation. My team have worked tirelessly to ensure those responsible are held to account and we achieve a measure of justice for the family. It has been an honour to do so.”

He warned of the dangers of carrying a knife, saying that doing so made it more likely that a blade would be used.

“Those actions will devastate the lives of everyone involved forever,” he said.

The knife used to murder Mr Innes last November has never been found.
