A former Massachusetts State Police lieutenant from Lanesborough has been indicted for allegedly bilking the agency out of at least $10,000.

The Berkshire Eagle reports John Giulino, 68, is among three former lieutenants to be charged in the ongoing state investigation into overtime abuse, according to a release from the state Attorney General's Office.

David Wilson, 57, of Charlton, and David Keefe, 52, of Norfolk, also were named in indictments returned Thursday by a Suffolk County grand jury. The indictments allege that the three were paid thousands of dollars for overtime hours they did not work.

All three were supervisors in Troop E, the unit previously assigned to oversee criminal and traffic enforcement of the Massachusetts Turnpike.

The Attorney General's Office began an investigation into overtime pay at Troop E based on a referral from state police after an internal audit that revealed potential misconduct. Criminal charges already have been filed against several troopers; dozens more remain under investigation.

In an attempt to conceal their misconduct, Wilson and Giulino allegedly submitted falsified traffic citations to make it appear that they had been issued during their overtime shifts, when in fact they were not issued during their overtime shifts or never issued at all, according to the release.

As commander of the Weston barracks, Keefe earned $207,878 in 2016, which included $55,960 in overtime pay. He allegedly submitted claims for payment of at least 170 hours he did not work, resulting in at least $17,000 in overpayment. Authorities allege that he regularly left early from these shifts and, at times, did not work them at all.

Each of the former lieutenants was charged with one count of larceny over $250 by single scheme, procurement fraud, and public employee standards of conduct violation (false/fraudulent claim to the employer). They will be arraigned in Suffolk Superior Court at a later date.
