A GREENOCK millionaire has told of his anguish at the loss of his son to suicide less than a year after his other son was murdered.

The body of Dr Brian Bonar's son, US Army veteran Adrian Bonar, 34, was discovered wrapped in plastic in the boot of a car in Anaheim, California, in October 2019.

Now he is dealing with a further tragedy after Adrian's younger brother Cannon, who was just 27, took his own life.

His dad says Cannon could no longer deal with the trauma of his brother's death.

Brian says his son 'went to a really dark place' after Adrian was murdered - and now blames the killers for his second devastating loss.

The Greenock-born entrepreneur said: "As far as I’m concerned, the guys who killed Adrian also killed Cannon.

"They took both my sons.

"Cannon was a bright boy with natural intelligence.

"He couldn’t get his head around how his brother died and it took him to a really dark place.

"He said he couldn’t deal with the fact Adrian was no longer here.

"He really struggled.

"We tried to help.

"I’m lucky enough to have the resources at my fingertips to do what I want, whenever I want - but I couldn’t save my boys."

Adrian, a dad-of-two, served three tours in Iraq as a decorated soldier but was honourably discharged after being diagnosed with post-traumatic stress disorder.

He fell into a life of drugs and depression and had a list of convictions for drugs and weapons offences.

Officers in the States arrested a man in connection with his death, and Brian says police have informed him three other men have now been arrested.

Strathclyde University graduate Brian, who leads Dalrada Financial Corp, says that Cannon had no history of mental health problems before his brother was killed.

He tried to help Adrian and even worked as a drug counsellor helping people who were battling addictions.

The Adrian Bonar Foundation, set up to help veterans suffering from PTSD, will now be renamed Brothers Forever Foundation after Cannon’s death.

It will be run by the brothers’ seven siblings.

Brian, who left Scotland for the United States in the 80s, said: "It’s not just servicemen and women who go to war zones who get mentally ill.

"Anyone who has gone through a traumatic experience is at risk.

"Cannon succumbed to the trauma of losing his brother."
