The same weapon was used in the murder of French soldiers in Montauban and Toulouse and of four people at a Jewish school in Toulouse. .Three of the soldiers were of North African origin, and another wounded soldier was Antillais. The regiment to which the soldiers belonged was in the news last year when several of its members were exposed as neo-Nazis and expelled.
Speculation based on these bare facts remains speculation. Nothing firm has yet emerged from the investigation, except that the same weapon was used in all three attacks and the killer rode a motorcycle.
