One of the four victims of a mysterious shooting in the French Alps last week has been identified as the grandmother of the two young girls who survived, police announced Monday. Zaina, 7, and Zeena al-Hilli, 4, survived the brutal shooting by hiding in the car where their mother and father were found dead. A passing cyclist was also killed. On Monday police bomb squads also arrived at the British family’s home, evacuating neighbors after officers found suspicious objects while searching the residence. Police are still working to discover what motivated the murders and who carried them out.
