Luka Magnotta refused to meet with Crowns psychiatrist

The psychiatrist hired by the Crown to give a second opinion on Luka Magnottas mental state was unable to provide a definitive diagnosis because Magnotta refused to meet with him, the first-degree murder trial heard on Tuesday.

Dr. Gilles Chamberland is expected to be the prosecutions final rebuttal witness, those whoare being called to counter the defenceassertionthat Magnotta is not criminally responsible due to mental illness.

Chamberland told the court, as many other psychiatrists have also testified, that Magnottas is a very complex case to study.

I think we can create a psychiatry course with only this case, Chamberland said, adding that theres not only a question of schizophrenia, but also bipolar and personality disorders, the possibility drugs played a role in the psychosis, and the chance Magnotta is simulating his symptoms.

• Luka Magnotta defence to wrap up its case

The psychiatrist sees two options in his analysis ofMagnottasbehaviour.

The first isthat the accused suffers from schizophrenia and that explains his behaviour throughout his life.

The second option is thatMagnottawas hospitalized in his late teens because he was taking drugs that simulated signs of schizophrenia, when in fact, he actually suffers from various personality disorders and is simply faking psychotic symptoms.

The second hypothesis,Chamberlandtestified, is the one that explains the situation much more easily.

The court will hear more fromChamberlandon Wednesday, along with details from his nine-page report that has been submitted asevidence.

Magnottahas admitted to committing the acts, including killing Lin, but he has pleaded not guilty to the five criminal charges laid against him due to mental illness.

The Crown alleges the killing was planned.

Personality disorder diagnosis before killing

Earlier in the day, the court heard from the last psychiatrist to seeMagnottabefore Jun Lin was killed. Dr. Joel Parissaid he found no signs of schizophrenia or psychosis during an hour-long assessment at Montreals Jewish General Hospitals outpatient psychiatry clinic.

Paris, who did not have access to the accuseds previous medical records, diagnosedMagnottaas having a borderline personality disorder, with unstable moods and relationships.

There was no evidence of an extended period of psychosis or chronic psychosis, Paris told the court, adding that what he heard fromMagnottadid not justify a diagnosis of schizophrenia or bipolar disorder.

During the April 2012 visit,Magnottatalked of being anxious, but he denied experiencing psychotic symptoms and only told the psychiatrist he was paranoid about getting fat.

He complained of impulsive behaviour, mood swings marked by highs and lows over several days, and chronic feelings of emptiness.

He also talked of compulsively pulling out his hair, causing bald spots.

Magnottatold Paris that he had been hospitalized four times as a teenager and that he had initially been diagnosed with paranoid schizophrenia.

ButMagnottaclaimed the previous diagnosis was fuelled by his cocaine use at the time and that it was later amended to bipolar disorder.

Paris told the court hes still not sure whyMagnottacame to the outpatient clinic that day.

Maybe what we offered him did not correspond to what he was looking for, Paris testified.

Diagnosis questioned

Under cross-examination, defence lawyerLucLeclairsuggested Paris has a bias towards diagnosing borderline personality disorder because thats his specialty.

Leclairalso accused Paris of dismissing schizophrenia without looking for the symptoms, a charge the doctor denied.

The psychiatrist admitted his diagnosis was tentative, as are all diagnoses after only one visit, he said.

Paris was the first of the Crowns rebuttal witnesses to testify, followed closely by two police officers who testified thatMagnottasphone records show he was looking to buy marijuana in the weeks before the killing.

Det-Sgt. FrancisDerome, a street drugs expert with the Montreal police department, testified the text messages showMagnottaused cannabis, but not other drugs.

Earlier in the day, the defence officially rested its case after hearing from its12thwitness, the lead police investigator who handled the case.

Magnottachose not to testify in his defence.

The judge has previously toldthe jury they could begin deliberating sometime in early December.
