BOSTON – A Hyannis man associated with the Nauti-Block gang was sentenced Wednesday in federal court in Boston for his role in trafficking large quantities of heroin throughout Cape Cod.

Oliver Hamilton, 26, was sentenced by U.S. District Court Chief Judge Patti B. Saris to 66 months in prison and three years of supervised release. In May 2017, Hamilton pleaded guilty to conspiracy to distribute and possess with the intent to distribute heroin and possession of heroin with the intent to distribute.

Hamilton was charged as part of the federal investigation into the Nauti-Block gang led by Denzel Chisholm, Christian Chapman, and Christopher Wilkins on Cape Cod that led to the indictment of 19 individuals. Chisholm and Chapman obtained heroin in New Bedford, and from other suppliers, and distributed the heroin to numerous drug dealers on Cape Cod, including Hamilton. Hamilton accepted responsibility for distributing between 100 and 400 grams of heroin.

Chapman pleaded guilty to heroin trafficking and was sentenced to eight years in prison. Wilkins pleaded guilty to multiple federal drug trafficking charges and is scheduled to be sentenced on Sept. 18, 2017. In June 2017, a federal jury convicted Chisholm of 11 counts of drug trafficking, including possession with intent to distribute one kilogram or more of heroin. He is scheduled to be sentenced on Sept. 15, 2017.
