UPDATED: Middlesex Sheriff's Department Sergeant Guilty on Cocaine Charges

Updated 10:39 p.m. with a statement from Middlesex County Sheriff Peter Koutoujian:

"After receiving an anonymous tip, the Middlesex Sheriff’s Office conducted an investigation into allegations of drug use by Sergeant Michael Dell’Isola. Our internal affairs unit immediately turned over information gathered during its probe to the Middlesex District Attorney’s Office and worked hand in hand with the State Police throughout the subsequent investigation.

The actions of Mr. Dell'Isola in this case are troubling, but they should not be allowed to taint the good work performed each and every day by the dedicated men and women of the Middlesex Sheriff’s Office.

I would like to thank the Massachusetts State Police and District Attorney Gerry Leone and his staff for their hard work and professionalism throughout this case."

A sergeant with the Middlesex County Sheriff's Department was found guilty Wednesday on charges that he received money and cocaine from an undercover state trooper, according to a press release from the Middlesex County District Attorney's office.

Michael Dell'Isola, 52, of Somerville, was found guilty after a six-day jury trial in Middlesex Superior Court, the press release says.

According to a statement from Middlesex County District Attorney Gerard Leone, "This defendant abused his position of authority by participating in illegal drug activities while on duty as a sergeant in the Middlesex Sheriff's Department."

According to the DA's office, Dell'Isola was pressuring an inmate to provide him with money and cocaine, and in an investigation into the matter, state police followed several phone calls in which Dell'Isola told an undercover officer he wanted the money and drugs.

On May 2, 2011, Dell'Isola met with an undercover officer at a coffee shop in Woburn, and the trooper handed Dell'Isola a coffee cup filled with cocaine and $500, the announcement says. He was subsequently arrested.

In court Wednesday, Middlesex Superior Court Judge Elizabeth Fahey sentenced Dell'Isola to one year in prison, six months to be served, and the remainder suspended for five years following probation conditions, which includes attending a drug treatment program, according to the announcement.
