The case is to be reinvestigated:
... the new inquiries will only investigate three theories considered the "most likely ones.""All of them are somehow connected with natural phenomena," said Alexander Kurennoi, the official representative of Russia's Prosecutor General.
"Crime is out of the question," he said, adding: "There is not a single proof, even an indirect one, to favor this (criminal) version. It was either an avalanche, a snow slab or a hurricane."
...
Next month prosecutors will fly to the site, and a range of experts and rescue workers will be involved in the investigation. Experts will conduct nine different examinations, including a forensic probe, which will help to fill in "a number of blank spots," Kurennoi added.
