Tonight, a major development in our story "298 Counts of Murder" – the hunt for the killers who shot down Malaysia Airlines Flight 17 from Amsterdam to Kuala Lampur in 2014.

A Russian Buk missile destroyed the Boeing 777 over Eastern Ukraine in Russian-backed rebel territory.

Dutch investigators pieced the wreckage together and used social media to document the missile launcher's movements from a Russian base.

After a two-year trial, a Dutch court earlier this month found three men guilty of murder. Two are former Russian security officers, the third is a Ukrainian who led pro-Russia troops. They were sentenced to life, but Russia refuses to extradite them to the Netherlands.
