potential new twist in the investigation into Rahmanullah Lakanwal, who ambushed two national service guard members, killing one and critically injuring another. Sources told the Daily Beast that they`re investigating a lead that Lakanwal might`ve been blackmailed by the Taliban, who may have threatened to murder his family in Afghanistan if he didn`t open fire on national guard troops.

The Daily Beast reported that a Taliban unit known as "Yarmouk 60," has made it a priority to track down and sometimes kill Afghans who helped US troops during the war. The anonymous source told the outlet that the potential blackmail wasn`t the "only line of inquiry," the investigators are looking into.
