Luka Rocco Magnotta's medical records on display at first-degree murder trial

MONTREAL - A psychiatrist who assessed Luka Rocco Magnotta for criminal responsibility also went through his voluminous medical records that suggested numerous highs and lows with schizophrenia.

Marie-Frederique Allard is testifying at Magnotta's murder trial today about his medical files, which she used to prepare a 127-page report regarding his responsibility in the slaying and dismemberment of Jun Lin.

The forensic psychiatrist has previously testified that she believes Magnotta was suffering from schizophrenia and in a psychotic state when he killed Lin in May 2012.

Allard says that while Magnotta knew what he was doing, he wasn't able to differentiate right from wrong.

Magnotta has admitted to killing the 33-year-old Chinese engineering student but pleaded not guilty by way of mental disorder.

The reports, which date back to 2001, suggest Magnotta was often concerned about others spying on him, heard voices and wasn't vigilant about taking medication to treat his schizophrenia.
