The brother of a taxi firm owner murdered 23 years ago has vowed to finally get justice for his loved ones.

Businessman Alexander Blue was attacked outside his luxury home in Glasgow’s West End in 2002 and died two days later from his head injuries.

His older brother Billy, 67, and mum Kathy, 91, are desperate to see the case solved after more than two decades of pain. But they fear they’re running out of time as yet another anniversary nears.

Billy recently underwent major surgery while Kathy requires constant care.

Billy believes his brother was killed by three men and has given detectives the name of a fourth – a Glasgow businessman – who sanctioned the hit.

He claims one man lured his brother out of his home while two others were waiting to overpower him.

In an exclusive interview with the Record, Billy said: “Alex needed someone familiar to put him at ease, to distract him, because Alex was a big guy and could look after himself.

“Alex was clearly taken by surprise by someone he trusted. He would not normally have given up without a struggle.”

He insists there is enough evidence to bring the killers to justice. Billy, of Robroyston, Glasgow, added: “It should never have taken this long and the evidence is there.

“The police are quite aware of who was behind my brother’s death. There is no mystery about this. The dogs on the street know who killed Alex.

“It’s time to bring those responsible to justice.”

Alex, then 41, was last seen studying business papers at about 8pm in his favourite coffee bar, just off Byres Road, on the night he was attacked.

Police got a telephone call just before 12.30am on June 25.

A neighbour had found Alex unconscious in a pool of blood in the drive of his Dundonald Road home.

The door of his Porsche was open, as was the door to his home. But nothing had been stolen. His injuries were so bad his mum didn’t recognise him when she saw him in hospital. In the early days of the probe, detectives faced major obstacles.

Officers hit a wall of silence, with few clues and no eye-witnesses.

Most of Alex’s business was conducted in cash with few deals recorded on paper.

His firm, the Taxi Centre, had a reported £7million annual turnover.

Alex had been concerned for his safety in the days before his murder and thought he was being watched.

Police Scotland said: “This is obviously still a difficult time for the Blue family who have suffered distress and heartache over the last two decades as they seek answers and justice for Alexander.

“Police Scotland never considers cases closed and this case remains under review.”
