...The day after the first arrests, the tide turned for the FLQ. On the night of October 17, an FLQ communiqué led police to a car parked near St. Hubert airport. In the trunk was the body of Pierre Laporte. He had been strangled to death.
It was the first political assassination in Canada since the murder of Thomas d'Arcy McGee 102 years earlier. Laporte's death would mark the beginning of the end of the FLQ as sympathy abruptly shifted away from the group.
On November 6, Bernard Lortie was arrested when the police raided the hiding place of the Laporte kidnappers. Three members escaped the raid but were captured in late December. Paul Rose and Francis Simard received life sentences for murder. Bernard Lortie was sentenced to 20 years in jail for kidnapping. Jacques Rose was convicted of being an accessory after the fact and sentenced to eight years in jail.
After two months of captivity, James Cross was released as part of a deal, which allowed five kidnappers to leave Canada. Over the years, all of the exiled FLQ members returned to Canada to face trial. They were all convicted of kidnapping and sentenced to jail terms. A sixth Cross kidnapper remained in Montreal and was arrested in July 1980 and convicted of kidnapping.
Several years later, after extensive investigation, it became apparent that the FLQ was not the major paramilitary organization many had believed. It was an informal group, organized in small, autonomous cells, whose members dreamed of a separate and socialist Quebec. At the time of the October Crisis, the group had no more than thirty-five members.
