Federal prosecutors want a career criminal from Dorchester to spend just over 18 years in prison for his conviction on a gun charge, citing his lengthy, violent record that includes several armed robberies and attacks.
In a court filing Friday, prosecutors recommended a 220-month sentence for Samuel O. Dixon, 46, writing that he “long ago committed himself to a lifetime of crime, mostly violent, and that previous terms of imprisonment have done nothing to alter his commitment to his craft.”
His public defender, Christopher Skinner, said he will request a 15-year term.
Dixon was convicted in US District Court in Boston in September of being a felon in possession of a firearm and ammunition, stemming from his arrest in February 2011 after police found a loaded .380-
caliber pistol in his apartment, along with narcotics and a digital scale, court records show. Boston police searched his residence after he allegedly sold heroin three times to an informant, prosecutors said. However, a drug charge was later dropped.
In Friday’s filing, authorities laid out Dixon’s extensive criminal history, which they said has spanned 27 years.
His record includes convictions for three armed bank robberies; a hold-up at knifepoint; an attempted robbery of a parking garage attendant, in which he struck the man in the head with a metal pipe; successful robberies of two other attendants; a stabbing; and disciplinary infractions while incarcerated, prosecutors wrote. They said he has amassed more than 15 convictions and has been arrested on “many, many other occasions.”
“The members of the public at large in general and the people living in the defendant’s neighborhood in particular deserve protection from further criminal conduct” by Dixon, prosecutors wrote.
His sentencing is scheduled for Wednesday.
