The local Taliban military unit, which was among the first to arrive at the scene of the plane crash, is being investigated for involvement in the theft.

Why am I suspecting this to end up being something like:
The Taliban is searching for the $1.2 million.
After days of searching, they still have not located the $900,000, but expect to soon find and return the $500,000.
After a full investigation, the $100,000 has not been located, but we expect the $10,000 to turn up soon.
And they hold a final press conference where they return the lost $3.50 to some suspiciously large person in a trench coat.
