BROCKTON — A Brockton man has been sentenced to two and a half years in prison for his role in a large-scale drug trafficking operation in Massachusetts.

The U.S. Attorney's Office said 24-year-old Tony Goncalves was sentenced on June 15 in federal court to 30 months in prison after pleading guilty last year to conspiracy to distribute heroin, fentanyl, cocaine, crack cocaine, oxycodone and marijuana.

Goncalves and his two brothers Djuna and Cody are at the center of the large drug trafficking ring that operated throughout southeastern Massachusetts, according to the office.

An investigation in 2018 revealed that Djuna, the leader of the organization, worked with his brothers and other people to sell large quantities of a variety of drugs from their family home and base of operations on Addison Avenue in Brockton.

According to the U.S. Attorney's Office, the neighborhood around the Brockton home has seen numerous murders, shootings and other violent crimes in the past several years.

Intercepted conversations between Tony and Djuna Goncalves showed that the brothers conspired to distribute marijuana from the Brockton base.

An unidentified person also fired several shots at Djuna there in October 2018, the office noted.

Authorities found and seized marijuana, packaging materials, scales, a kilo press, fentanyl, firearms and ammunition at the home in a subsequent search.

The three brothers were among 17 defendants caught and indicted as part of the drug trafficking ring following the investigation.

Following his prison term, Tony Goncalves will spend another three years on probation.

Djuna and Cody Goncalves have also both pleaded guilty to their roles in the organization.

The group's leader, Djuna, is set to be sentenced on June 30, while their brother Cody is set to be sentenced on June 21.
