KIEV, UKRAINE (AP) -
It's one of the biggest mysteries hanging over the violence that drove Ukraine's president from power last month: Who sent the snipers to Kiev to take aim at protesters, police and bystanders?
Ukrainian authorities are investigating the bloodbath, which left more than 100 people dead. A majority of them were shot by snipers.
The focus of the investigation has shifted from the government of ousted President Viktor Yanukovych to Vladimir Putin's Russia. The theory is that the Kremlin wanted to create mayhem as a pretext for a military incursion.
Russia, though, suggests that the snipers were organized by opposition leaders who wanted to whip up local and international outrage against the government.
This much is known: Snipers firing powerful rifles from rooftops and windows shot scores of people in the heart of Kiev. Some victims were opposition protesters, but many were civilian bystanders who were clearly not involved in the clashes. The dead included medics, as well as police officers.
