The judge at a fatality inquiry believes changes already made to the psychiatric ward at Edmonton's Royal Alexandra Hospital should be enough to keep patients safe in the future, while the brother of the man whose death prompted the inquiry says there's no justice in the findings.

The report from provincial court Judge Larry Anderson, released Thursday, examines the death of patient Dwayne Roger Roy. Roy, 57, was killed by another patient on the psychiatric ward of the Edmonton hospital on July 30, 2007.

Roy was sleeping in his bed around 3:30 that morning when Jean Francois Sheehy, the patient next to him, suddenly attacked. Sheehy stabbed Roy several times in his room. Roy was able to escape but Sheehy attacked him again in the hallway.

When security staff arrived, Sheehy was on top of Roy, strangling him. Sheehy then slowly stood up and stomped on Roy's head, crushing his skull, the report says.

It is believed that Sheehy brought a knife back into the ward the previous day when he had been given approval to leave the hospital briefly to check on his apartment and find his vehicle keys.

Sheehy was charged with second-degree murder but ultimately was found not criminally responsible due to his mental illness.

According to evidence heard during the criminal proccedings, Sheehy was suffering from a delusional disorder, described as parnaoid schizophrenia or schizoaffective disorder, bipolar type.

Sheehy didn't just believe that Roy wanted to kill him; he believed Roy was giving direction to others at the hospital, the judge writes.

"It is not clear from the evidence what Mr. Roy may have said or done, if anything, in order to become incorporated into Mr. Sheehy's delusions. There is little doubt, however, that the attack on Mr. Roy was based upon the delusional thinking of Mr. Sheehy."

The hospital made changes after the murder. Searches of patients' belongings is now mandatory and staff now evaluate newly admitted patients using a special risk assessment scale.

In the report, the judge calls those changes "prudent" and says they will improve the safety of staff and patients on the ward. He saw no need to add any further recommendations to what has already been put in place.

'No justice to it'

Mark Snaterse, director of mental health for Alberta Health Services, was pleased with the judge's findings.

"I think to some degree it validates the steps that we did take and it acknowledges that the steps that we took have improved the element of safety and securability on the unit," he said. "So I'm happy with that."

But Lucien Roy, the victim's brother, said he's outraged that no one has been punished for his brother's death and hospitals still won't be safer.

"Other than the report making people more aware, there really is not too much change in what's going to happen into the future," he said. "He did die in vain. There was no justice to it. There was no need for it."
