A Taunton man was sentenced to four to six years in prison on gun and drug charges.

Gregg Miliote, Director of Communications for the Bristol County District Attorney's Office, says that 30-year-old Silas Dobson entered a guilty plea on Tuesday in Fall River Superior Court to charges of being a felon in possession of ammunition and unlawful possession of heroin.

Miliote says that on October 12, 2015 Dobson's girlfriend called Taunton Police after he allegedly threatened her.

Officers arrived on scene and observed Dobson walking away from the apartment he shared with his girlfriend.

After stopping Dobson officers found him to be in possession of a small amount of heroin.

A search of his apartment then uncovered 42 9 millimeter rounds of ammunition.

Dobson was previously convicted of, and serve jail time for, charges ranging from violating restraining orders to assaults to firearm possession.

“This defendant is a career criminal who does not belong on the streets of Taunton, said District Attorney Quinn. “Nothing good can come from a felon unlawfully possessing so much ammunition.”
