NORTH ADAMS, Mass. — Two local men were arrested Thursday night and are facing felony charges in connection to recent break-ins and copper theft at the Blackinton Mill.

Sam Malinowski, 22, of North Adams, and Dylan Forde, 24, of the town of Florida, were arraigned Friday morning at Northern Berkshire District Court and both were charged with counts of breaking and entering, destruction of property (of a value over $250) and malicious larceny (of a value over $250). According to Commissioner of Public Safety E. John Morocco,  "quite a large amount of copper" was stolen from the mill over the last several days.

"It looked like they maybe had been taking pieces out for some time," Morocco said.

David Moresi, building manager of the Blackinton Mill, said the stolen goods included copper plumbing, electrical wire pipes and feeder cables. He estimated the scrap value taken was in the vicinity of $3,000, while the cost of damages is "anywhere between $65,000 to $80,000."

"We'll be looking to get full prosecution to the fullest extent of the law," Moresi said. "This band of thieves had been hitting [the mill] since last weekend, and they just kept going back. They set up shop like it was their job."

According to police reports, North Adams police stopped the suspects, who were passengers in a 2001 Chevy Cavalier, on Thursday night at approximately 8 p.m. in the Big Y parking lot.

"The North Adams Police was phenomenal on this," Moresi said. "You don't often catch copper thieves."

On Friday afternoon, Sgt. James Burdick said the break-ins were "still under investigation."

May 13: NORTH ADAMS, Mass. — State police and several K-9 units responded to "suspicious activity" late Thursday afternoon at the Blackinton Mill, located on the corner of Massachusetts Avenue and Ashton Avenue.

"[Police] thought somebody was inside, that someone had broken in," North Adams Police Sgt. James Foley said Thursday night. "They ended up searching the building and didn't end up locating anybody."

According to police reports, North Adams police first arrived at the scene at 2 p.m., and was soon followed by three more units.

By 3:30 p.m., two North Adams cruisers, Pittsfield K-9 and state police K-9 vehicles were parked on the east entrance of the mill, according to eye-witness accounts. A Williamstown K-9 unit was located on the west end, while two more North Adams cruisers were outside the north perimeter on Massachusetts Avenue.

Foley confirmed that "infrared heat sensors" were used in an attempt to find the alleged suspect. He said there are "several people of interest" who police suspect broke into the mill, but he couldn't reveal their identities.

According to the police report, the scene was cleared at 4:52 p.m.

The mill was recently sold to two New York developers with plans to turn it into a commercial and residential development.
