As the police chief in a Washington, DC suburb, Charles Moose led the investigation of the area's sniper shootings last year. And now, he's resigning from that post.
A police spokeswoman in Montgomery County, Maryland confirms that Moose is stepping down.
He has been at odds with county officials over his plan to write a book about the sniper investigation.
The county ethics commission ordered him to drop the project, but Moose challenged the decision, both in county circuit court and in a federal lawsuit that claimed his free-speech rights had been violated.
The county executive tells a Washington radio station (WTOP) that Moose gave him a letter on Monday saying he'll resign on June 28.
