"There is a court case on March 9 2020 against four people for murder", Silene Fredriksz, whose son and daughter-in-law were killed in the disaster, told reporters after family members were briefed on the charges.
Global investigators are poised to name four suspects they believe are responsible for shooting down MH17 and level charges for the first time.

Passenger flight MH17 was en route from Amsterdam to Kuala Lumpur when it was shot down over conflict-hit Ukraine.
JIT is the Dutch-led authority, comprised from representatives from five countries, which is investigating the Malaysia Airlines Flight MH17 crash over eastern Ukraine in 2014.
Moscow has said it does not trust the investigation.
Investigative website Bellingcat on Wednesday said it had identified a number of separatist fighters who were responsible for misidentifying MH17 as a target and for the escort and deployment of the Buk missile launcher that downed the airplane.
The Russian government denies having lent any support to pro-Russia rebels fighting Ukrainian government troops and also denies any involvement in shooting down MH17.
While the Netherlands and Australia hold Russian Federation responsible for the shooting, Putin has said that while the incident was a "terrible tragedy" Moscow was not to blame. The first three are Russian, and Kharchenko is Ukrainian, Dutch prosecutor Fred Westerbeke said.
Once the names and charges have been announced, the next step would be to attempt to put the accused on trial.
