A Boston man with felony convictions for violence and drug trafficking on his record was indicted Tuesday in connection with allegedly purchasing firearms in New Hampshire and transporting them to Dorchester and other areas of Massachusetts. Shayne Parker, 41, of Boston faces one count of being a felon in possession of ammunition and one count of unlawful transportation of firearms in Massachusetts.

The charge of being a felon in possession of ammunition provides for a sentence of no greater than 10 years in prison, three years of supervised release, and a fine of $250,000. The charge of unlawful transportation of firearms provides for a sentence of no greater than five years in prison, three years supervised release, and a $250,000 fine.

The office of US Attorney Carmen Ortiz announced the indictment, saying Parker and another man from Massachusetts made illegal "straw purchases" from New Hampshire gun dealers and transported an estimated 20 to 25 firearms into Massachusetts. Authorities previously charged four others in US District Court in New Hampshire in connection with the alleged gun trafficking scheme. The firearms were often traded for illegal narcotics, according to prosecutors, and "numerous guns purchased and transported have been recovered at crime scenes on the streets of Boston."

Former Gov. Deval Patrick last August signed a law aimed at reducing gun violence by creating new firearms crimes such as assault and battery by discharge of a firearm and enhancing sentences for firearms crimes such as trafficking in firearms and gun related deaths.

The law also required courts to transmit mental health and substance abuse commitments, domestic violence convictions, restraining orders and guardianship appointments to the criminal justice information system for inclusion in a National Instant Criminal Background Check System available to states for firearms licensing. The law also made a felony conviction a lifetime disqualifier for firearms licenses and added a suitability determination to firearms identification cards issued by local licensing authorities.
