HYANNIS – From Barnstable Police: On October 31, 2026, at approximately 3:55 AM, Barnstable Police Officers responded to Guerra Jewelers, located at 33 Bassett Lane in Hyannis, following a reported commercial alarm activation. Upon arrival, officers discovered that the business had been forcibly entered and numerous items of jewelry had been stolen.
The business owner reported the theft of multiple gold and silver items, including chains, pendants, and rings. Surveillance footage obtained during the investigation showed a suspect, armed with a firearm, forcibly kicking in the front door before entering the business, smashing the display cases and stealing merchandise.
During the course of the investigation, detectives received information identifying a possible suspect as Diego Goncalves De Souza, 34, of Hyannis. Detectives developed additional evidence linking De Souza to the break-in, including witness statements, surveillance footage, vehicle information, and the identification of jewelry believed to have been stolen during the incident.

Working in coordination with the Massachusetts State Police Troop F and airport authorities, BPD Detectives located De Souza at Logan Airport on the morning of November 1, 2026.
De Souza was taken into custody without incident prior to boarding his flight. He was subsequently transported to the Barnstable Police Department for booking.
At the time of his arrest, detectives recovered multiple pieces of jewelry from De Souza’s person and belongings. The items were seized as evidence and are being processed as part of the ongoing investigation.
