Man with automatic weapon arrested after burst of gunfire on Bowdoin Street in Dorchester, police say

A Dorchester man faces a variety of gun charges - including possession of a machine gun - after he led BPD gang-unit officers and state troopers on a foot chase Tuesday evening, police say.

Police say that gang-unit officers and troopers were on patrol on Bowdoin Street near Hamilton Street around 6 pm. when they heard what sounded like "rapid shots being fired from a machine gun" and smelled gunshot residue. They then spotted "multiple spent shell casings in the middle of the roadway."

As Officers were establishing a crime scene, additional 911 calls and witnesses provided Officers with a description of a possible suspect and the exact direction he was fleeing towards. With this new information, Officers expanded their search and located a possible suspect at 16 Olney St.

Upon seeing Officers, the suspect immediately fled into the rear of 16 Olney St, scaled a fence, and began running towards Bowdoin St. and Topliff St. Officers began a foot pursuit and apprehended the suspect on Bowdoin St. Officers recovered a firearm that had fallen onto the ground from the suspects waistband when they were placing him in custody.

District C-11 Detectives responded and the firearm was determined to be a black Glock 23 .40 Caliber with an extended magazine capable of holding twenty-two rounds of ammunition. A Syr-switch which converts a semi-automatic handgun into a fully automatic machine gun was also attached to the firearm.

John Rodrigues Carvalho, 20, of Dorchester, was charged with illegal possession of a firearm, possession of a machine gun, possession of a large-capacity feeding device and trespassing, police say.

Innocent, etc.
