The Crown is proposing a global sentence of 14 years for the man charged with holding nine people hostage in the WCB building downtown two years ago.

"His conduct was patently dangerous," Crown prosecutor Lisa Tchir told the court Monday. "Deterrence and denunciation should be paramount"

Late last week, Patrick Clayton testified in his sentencing hearing, and apologized to the victims of the hours-long standoff.

Clayton began his testimony by reading a one and a half page statement, stating:

"I would like to express my utmost and sincerest apologies to every person in the conference room that day."

As Clayton was questioned by his lawyer he related what had happened over the years since he had injured his knee while at work.

Over the years between the injury and the hostage-taking, Clayton said a WCB-appointed doctor made his injury worse, in later years he learned his issue was not appealable with the WCB and he said he began self-medicating to cope.

"They pretty much bullied me into non-existence…[they] turned me into a person I did not want to be," Clayton said in court.

When cross-examined by the Crown, Clayton admitted to using crack cocaine bi-weekly, for years before he was hurt at work, and that same knee was injured four times before the worksite injury.

He had injured his knee several years before while shoveling snow then had surgery for it.

A psychologist testified Thursday, and said Clayton acted out of obsessive brooding, drug use and self-pity, and that his intentions were to not harm anyone.

However, the psychologist said putting Clayton behind bars wouldn't help him – but recommended halfway measures of community sentencing or halfway incarceration as alternatives.

On Thursday the WCB also weighed in, with a statement from CEO Guy Kerr who said the WCB upgraded security after the incident, which cost $6.6 million – plus yearly security personnel fees of $750,000.

Clayton was charged with nine counts of unlawful confinement, six counts of pointing a firearm, possession of an offensive weapon dangerous to the public, careless use or storage of a firearm and use of a firearm during the commission of an offence.
