Ukraine’s authorities are still investigating, but seem to be over their head with this case as they are with so many other complicated ones. A team of Ukrainian journalists is conducting its own investigation and the Kyiv Post wishes them well in helping to identify who is responsible for the car bombing.

But with each passing day that no suspects are identified or arrested, a little more hope is lost. While only three weeks have gone by, Ukraine’s authorities have no track record of solving high-profile murders.

The circumstances of Sheremet’s murder, combined with Russian President Vladimir Putin’s Aug. 10 vitriolic attacks on Ukraine and escalation of war (see story on page 1), increase our suspicion that the Kremlin used Sheremet as a pawn to help whip up even more anti-Ukrainian fervor among Russians. The Aug. 6 attempted assassination of Kremlin-backed separatist leader Igor Plotnitsky could have served the same purpose.

We hope solid evidence and hard facts will soon end all speculation.
