A manhunt is underway in France for a serial gunman suspected of killing four people at a Jewish school on Monday. The same shooter is believed to have killed three French soldiers of African and Caribbean descent in earlier attacks this month. Authorities say the same gun and motorcycle were used in those attacks, and the shooter wore a motorcycle helmet. New reports say the gunman wore a small video camera around his neck and may have filmed the attack that killed three children and a rabbi at a Jewish school in Toulouse.
