Background

Born in Normandin in the Saguenay-Lac-Saint-Jean region of Quebec. He studied medicine at Université Laval, in Quebec City, and psychiatry at McGill University, in Montreal.

In 1975, after serving as a psychiatrist for the Canadian Forces, he started working with assault offenders and participated in numerous trials as an expert witness in the psychiatric domain.

Mailloux was assigned to the Denis Lortie case. According to Mailloux, Lortie had paranoid schizophrenia and had organized his crime during a psychotic episode, believing he was acting on instructions from God. Nevertheless, in 1985, Lortie was convicted of first-degree murder, but a new trial was ordered due to legal errors. Lortie pleaded guilty to reduced charges of second-degree murder in 1987.

Mailloux latterly practised in and around the Trois-Rivières area.

On January 12, 2024, Mailloux died in Trois-Rivières, by assisted suicide, following unspecified complications from a renal infection at the age of 74.
