Longueuil fatal crash: Parti Québecois calls for independent review

Quebec's opposition parties are calling for an independent review after a police officer involved in an anti-corruption unit operation crashed into a car, killing a five-year-old boy. 

The incident happened last February, at the intersection of Gaétan-Boucher and Davis boulevards in Longueuil, on Montreal's South Shore.

According to documents obtained by the newspaper La Presse, four unmarked Sûreté du Québec cars were involved in a police surveillance operation aimed at Robert Parent, the former director of the Quebec Liberal Party.

The operation was carried out by Quebec’s anti-corruption police unit (UPAC).

French newspaper La Presse reported that around 8 a.m. on Feb. 13, the police officers reportedly accelerated to catch up with the car that was tailing Parent’s Mercedes.

A police officer driving a black Camry sped through the intersection, crashing into the grey Kia sedan carrying Mike Belance, his five-year-old son and his 10-year-old stepdaughter.

The young boy suffered a head trauma and died Feb. 17 in hospital. The girl only suffered minor injuries.

An SQ document established that the police tail was part of an investigation related to corruption, breach of trust and illegal political party financing.

Crown: No outside influence

Quebec's Director of Criminal and Penal Prosecutions (DPCP) is denying that pressure from any outside groups influenced its decision not to press charges against an officer involved in a fatal car crash in Longueuil, Que.

The DPCP issued a statement on Friday, in response to the latest revelations. 

It said that its legal analysis of the case was not rushed, and that no outside group influenced its decision.

"The DPCP ensures that prosecutors handle its cases independent of any external influence, be it police or political, and without yielding to pressure from the media," it said.
