Two York County men who stole numerous guns as members of a burglary ring pleaded guilty Monday in U.S. District Court in Portland to charges of conspiracy and possession of stolen firearms.

Chris Michaud, 23, of Limerick and Cole Meserve, 21, of Standish were part of a ring that stole 11 guns, including a .50-caliber sniper rifle, during burglaries in York, Cumberland and Oxford counties, according to police.

Acting on a tip, sheriff’s deputies found the guns last November in a home on Hurlin Smith Road in Buxton, Stephen McCausland, spokesman for the Maine Department of Public Safety, said at the time. They included the .50-caliber sniper rifle, three Ruger special edition pistols and three assault rifles.

McCausland said the three suspects kicked in doors to commit more than 20 daytime burglaries at homes in Sebago, Brownfield, Denmark, Gorham, Limington, Limerick, Dayton and Lyman. The burglaries had been occurring since October.

Trooper Jeremy Forbes, an investigator at the state police barracks in Alfred, said the three were using the money they got for the stolen items to buy drugs, according to McCausland.

Investigators searched houses in Limerick and Buxton and a self-storage facility in Limerick after the tip last November. They recovered several guns, three off-road motorcycles, televisions, computers and other electronic devices. They also seized a large amount of marijuana.

Though Michaud and Meserve were initially accused of stealing at least 11 firearms, they admitted only to possessing two rifles and a pistol under the terms of their plea agreement in federal court.

A third accused conspirator, 21-year-old Amber Meserve of Limerick, is due to appear in court on Oct. 1 for a change of plea hearing to a conspiracy charge.

Cole Meserve and Michaud both remain in federal custody pending their sentencing hearings. The sentencing dates were not immediately available. They each face up to 10 years in federal prison on the firearms possession charge and a fine of up to $250,000.

Amber Meserve remains free on an unsecured bond for $10,000, according to court records. She faces up to five years in federal prison if convicted of the conspiracy charge.
