As rumor and speculation continues to swirl around last week's murder of Russian opposition leader Boris Nemtsov outside the Kremlin, a new video capturing the moments just after the shooting has surfaced. The new dashcam video footage corroborates reports of a white car at the scene that was potentially used as a getaway vehicle, but provides few clues on the identity of the mystery assassin.
Nemtsov, a former deputy prime minister and outspoken critic of Russian President Vladimir Putin, was gunned down in open air last week, taking four bullets to the back from behind as he walked along Bolshoi Moskvoretsky Bridge with his Ukrainian girlfriend Anna Duritskaya on February 27, just steps away from Russia's seat of power.
The new video that surfaced Wednesday, filmed from a car driving toward the Kremlin and then across the bridge past the scene just four minutes after the shooting, corroborates existing grainy CCTV footage of the event captured by a local television station's traffic camera.
The CCTV footage shows the scene before and after the incident, but a passing truck obscures the moment bullets were fired. It did capture an unknown figure - potentially the assassin - getting into a decelerating white car and leaving the scene.
The new dashcam video shows the truck parked at the scene at 00:50, blocking Nemtsov's body from view, while a white vehicle remains stationary behind it. No other videos or angles of the shooting have surfaced yet.

Days after the murder, Russia's Federal Security Service (FSB) told state news agency RIA Novosti that surveillance cameras in the area were functioning, but pointed inward, toward the Kremlin, and did not capture the murder. The Bolshoi Moskvoretsky Bridge is not within the service's "zone of responsibility," the agency said.
However, well-known photographer, blogger, and activist Mitya Aleshkovsky later accused the Kremlin of lying, claiming he had taken a photo of the building on the night of the murder, which clearly shows a Kremlin tower security camera pointing outward, toward the bridge.
FSB Director Alexander Bortnikov said Wednesday that the agency has so far identified several possible suspects as part of its investigation, Russian news agencies reported.
"There are always suspects," he told Russian news outlets, without elaborating.

Tens of thousands of mourners marched through Moscow over the weekend, some carrying flowers and others bearing signs that read "I am Boris Nemtsov" - a reference to the phrase "I am Charlie" that arose out of the deadly terror attacks in January at the Paris office of satirical magazine Charlie Hebdo.
Putin has publicly condemned the murder of Nemtsov, his former colleague who served with him in Boris Yeltsin's administration in the 1990s. A spokesman for Putin has said Nemtsov was killed as a "provocation" against the state.
The country's powerful investigative committee also suggested the assassination was connected with "internal Ukrainian events," implying that Kiev ordered the hit on the Nemtsov - a liberal, pro-Western supporter of Ukraine - to discredit Moscow. It also offered a theory that the assassination was tied to Islamic terrorists upset at Nemtsov's support for the Charlie Hebdo journalists shot in Paris.
