MH17 investigators offer proof missile originated from Russian military unit

Investigators probing the downing of flight M-H-17 say the missile which brought down the plane over eastern Ukraine originated from a Russian military brigade. The international Joint Investigation Team's finding provides some new answers for family and friends of the hundreds who died on board. And as Russia continues to deny the claims, Australia and other nations involved in the investigation are considering options to prosecute those responsible.
