PORTLAND, Maine — Two York County men pleaded guilty Monday in U.S. District Court to one count each of conspiracy to possess stolen firearms and possession of stolen firearms, according to the U.S. attorney’s office.

By pleading guilty, Christopher Michaud, 23, of Limerick and Cole Meserve, 21, of Standish admitted that between May and November 2014, they committed a series of residential and commercial burglaries in York, Cumberland and Oxford counties in order to steal items that could be sold for cash or traded for drugs. During an Oct. 1, 2014, residential burglary in Buxton, the duo stole three guns, according to the prosecution version of events to which they pleaded guilty.

Those firearms were recovered on Nov. 21, 2014, during the execution of search warrants at a storage unit in Limerick that was rented by Michaud, according to the U.S. attorney’s office. Other recovered stolen items included motorcycles, electronics and tools.

Sentencing dates for Michaud and Meserve have not been set. They have been held without bail since their arrests on the federal charges in May.

A co-defendant, Amber Meserve, 22, of Limerick, is scheduled to plead guilty Thursday in federal court in Portland to one count of conspiracy to possess stolen firearms. She is accused of driving her co-conspirators to and from the burglary locations and acting as a lookout.

The defendants face up to five years in federal prison on the conspiracy charge and up to 10 years on the firearms possession charge. They each also face fines of up to $250,000.

Information about the status of state charges related to the burglaries was not available Tuesday.

The case was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Maine Drug Enforcement Agency, the Maine State Police and the Office of the Maine Attorney General, with assistance from the Buxton Police Department and Cumberland and York county sheriff’s offices, the U.S. attorney’s office said.
