Matthew de Grood 'clearly was psychotic' when he stabbed 5, psychiatrist testifies

Matthew de Grood "clearly was psychotic," not faking the state, and thought one of the five people he stabbed to death at a Calgary house party was a werewolf about to kill him, a forensic psychiatrist testified at his murder trial Wednesday.

Matthew deGrood"clearly was psychotic" and thought one of the five people he stabbed to death at a Calgary house party was a werewolf about to kill him, forensic psychiatrists testified at his murder trial Wednesday.

Dr. AlbertoChoyand Dr. Lenka Zedkovacolleagues at the Alberta Hospital in Edmonton testified that they believe de Grood should be found not criminally responsible on the five counts of first-degree murder he is facing.

"He understood that he was stabbing and killing them," saidChoy, who examined deGrood several months after the killings."But he wasn't able to establish that what he was doing was morally wrong."

The 24-year-old admitted to stabbing Lawrence Hong, 27, Joshua Hunter, 23, Kaitlin Perras, 23, Zackariah Rathwell, 21, and Jordan Segura, 22, at a house party in the Brentwood neighbourhood in April 2014, but has pleaded not guilty. The goal of his lawyer is to have deGrood, once a promising university student heading to law school in the fall of 2014, deemed not criminally responsible (NCR).

In preparing their independent reports, Choy and Zedkova pored through de Grood's text messages, interviewed his parents and reviewed medical records from after his arrest, in addition to interviewing the now 24-year-old.

Zedkova who spent a total of14 hours with de Grood for her assessment said on the night of the party de Groodfeared he would be killed.

"He didn't feel any other emotions, really. Just fear."

She testified that atthe party, de Grood was speaking with Rathwell about Buddhism.Rathwell brought up the subject of death and put his hand on de Grood's shoulder.

De Grood perceived it as a threat and told Zedkova he heard a demonic voice he believed to be the sun god saying "kill them all before they kill you."

"To him, it marked the beginning of the war," she said.

Choy was unable to put a label on de Grood's mental health condition, but Zedkovasaid he likely suffers from schizophrenia.

"He intended to kill these individuals ... because he believed his life was in danger," she said.

"My opinion is that he did not know what he was doing was morally wrong ... [He believed] it was self defence."

Facebookposts and ideas aboutwerewolves, vampires and the end of the world all played intoChoy'sanalysis of deGrood'smental health.

De Groodbelieved he was at war with vampires and werewolvesand had to kill before he was killed, Choy said.

Choy also said de Grood was at timessuicidal after the stabbings and worried staff members at the Southern Alberta Forensic Psychiatric Centrethe facility where he was held after his arrestweretrying to kill him.

Some of the questions put to Choy and Zedkova under cross-examination centred around de Grood's awareness of the fact that an NCR defence could be available to him.

Choysaid it wasinitially concerning, butthe"mountain of evidence" from different sources satisfied him that deGroodwasn't faking or exaggerating his psychotic symptoms and was "severely ill."

The NCR defence "was his preference," according to Zedkova who went on to say she felt de Grood was "simply being honest."

Unbiased medical professionals

Though Choy and Zedkovawerecalled to testify by the defence, de Grood's lawyer, Allan Fay, told media outside the courtroom that it's important for the public to understand the experts who are testifying over the next two days are unbiased medical professionals.

"This isn't some story we've made up, this isn't some hired gun that I've paid a lot of money to come in to give this kind of testimony to give my client an easy out," said Fay.

"They're not hired by me. They're paid, ultimately, by the province. But regardless of who pays their bills, they're hired to give an unbiased opinion as to my client's condition."

Fay said he's aware the not criminally responsible defence doesn't sit well withsome members of the public.

"It is very important that the public know that my client is not getting any special breaks because his father is a police officer. My client isn't trying to avail himself of a trumped-up defence. My client was mentally ill when this occurred to the point that he was incapable of appreciating the moral wrongness of what he was doing."

If de Groodis found NCR by the judge hearing the trial in Court of Queen's Bench, then hewould be sent to a psychiatric facility rather than a prison.

On Monday, court heard evidence thatde Groodsent ominous messages in the hours before the killings and told friends at the party that he thought the end of the world was imminent.

De Grood's father, a 30-year veteran of the Calgary Police Service, considered swearing a mental health warrant in the days before the killings as he and his wife had become increasingly concerned about their son's apparently deteriorating mental health, according to an agreed statement of facts.

The trial continues on Thursday with Fay set to call a psychologist who will be the final witness. Closing arguments are expected to be presented on Tuesday.
