Police have arrested a Wells woman in Maine and her boyfriend in New Hampshire, both on charges that they were operating a methamphetamine manufacturing lab in a camper where they lived with their three children.

Jennifer Boudle, 28, was arrested Monday during a traffic stop in Wells on a warrant for a charge of unlawful operation of a meth lab. Her boyfriend, John Regan, 41, of Wells, was arrested Tuesday in Concord, New Hampshire, according to Stephen McCausland, spokesman for the Maine Department of Public Safety.

Their arrests come after local police and agents from both the Maine Drug Enforcement Agency and federal Drug Enforcement Administration executed a search warrant at their home on Nov. 16 at 859 Post Road in Wells and discovered a meth lab in the camper.

The investigators found Boudle, Regan and their three children, whose ages range from infancy to 10 years old at the camper. Investigators allowed the family to leave as they prepared their paperwork to search the camper. They made the arrests after completing their investigation and obtaining arrest warrants for the parents on Dec. 23, McCausland said in a news release.

McCausland said the children are being cared for by other relatives.

Boudle was taken to the Wells Police Department after her arrest and freed on $500 bail. Regan remains in custody in New Hampshire while authorities arrange for his extradition back to Maine to face the charge here.

Unlawful operation of a meth lab is a Class B felony under state law punishable by up to 10 years in prison.

Authorities in Maine have seen a spike in the number of meth manufacturing labs here in recent years, including an increasing number in more densely populated areas in York, Cumberland and Penobscot counties, Roy McKinney, the director of the Maine Drug Enforcement Agency, said in an interview last week.

The number of meth lab incidents in Maine rose from 7 in 2011 to 15 in 2012, 20 in 2013, then 37 in 2014 and 55 so far in 2015 with two days left in the year.

The MDEA has also dedicated more resources into combating meth manufacturing here, from 17 investigations in 2011 to 76 investigations in 2015, as of Nov. 30.
