Feds move to dismiss McClendon indictment

As expected, federal prosecutors have moved to dismiss the indictment of Chesapeake Energy founder Aubrey McClendon, "for the reason that such action would best meet the ends of justice in that the defendant is now deceased."

The motion was filed in U.S. District Court in Oklahoma City this afternoon, the day after McClendon died in a fiery one-car crash. He was 56 years old.

But while the case against McClendon is expected to end, a law enforcement source tells CNBC that the Justice Department's broader investigation into possible collusion in the oil and natural gas industry is ongoing.

In announcing McClendon's indictment Tuesday, the Justice Department billed it as "the first case resulting from an ongoing federal antitrust investigation into price fixing, bid rigging and other anticompetitive conduct in the oil and natural gas industry."
