A second man who was charged with committing dozens of residential burglaries throughout the state after East Lyme police discovered a storage unit full of stolen goods pleaded guilty Wednesday in exchange for a 25-year-prison sentence.

Mark Missino, 46, of Waterford pleaded guilty in Superior Court in Stamford to five counts of third-degree burglary, violating the state’s Corrupt Organizations and Racketeering statute and first-degree larceny.

The case had been transferred to the Stamford-Norwalk Judicial District because many of the burglaries occurred in that part of the state, but New London prosecutor Paul J. Narducci remained involved and attended Wednesday’s proceeding. He said Missino pleaded guilty to committing burglaries in the Stamford area and in southeastern Connecticut and would be sentenced Jan. 30 to 40 years in prison, suspended after 25 years served followed by five years of probation.

Missino’s co-defendant, Bernard McAllister, 42, of Lisbon had previously pleaded guilty to state and federal charges. He is to be sentenced on Nov. 22 to 16 years in prison for the state case and faces 15 years to life when he is sentenced in federal court for possession of firearms by a previously convicted felon. No sentencing date has been set in that matter.

Missino also has a pending case in federal court.

McAllister and Missino were arrested in November 2010 after East Lyme police caught them fleeing from a storage unit containing more than 8,000 stolen items. State prosecutors charged them with burglarizing dozens of homes from Stonington to Greenwich between 2008 and 2010. After he was arrested, McAllister admitted he had been planning to leave the country, according to authorities.

The federal government charged the two men with possession of 19 stolen firearms, including long guns, revolvers and semi-automatic pistols that were found in the storage locker. It is a violation of federal law for a person previously convicted of a felony offense to possess a firearm or ammunition that has moved in interstate or foreign commerce.
