The Paris attacks trial and the three who slipped away

The trial in Paris of 14 people accused of complicity in the separate January 2015 terrorist attacks in the French capital against Charlie Hebdo magazine, a kosher store, and a policewoman, which left 17 victims dead, opened on Wednesday. Absent from the hearings are three defendants whose fate or eventual whereabouts is unknown. In this second of a two-part report, Matthieu Suc details the story of how the three got away, and the evidence that at least one of them is alive and hiding from justice in the Middle East.
