18-year-old charged with murder after Chelsea brawl

The suspect is held without bail.

A brawl in Chelsea Saturday night ended with an 18-year-old being arrested for murder, the Suffolk County District Attorney announced Monday.

Joksin Briones-Blandon, of Medford, was arraigned on a charge of first-degree murder in Chelsea District Court on Monday. He was held without bail, with a probable cause hearing set for August 20.

Chelsea police responded to reports of a brawl at the intersection of Highland and Grove streets on Saturday night. Santos Cartegena, 44 suffered multiple stab wounds, according to DA Kevin Hayden’s office. He was transported to Beth Israel Hospital, where he died from his injuries early Sunday morning.

Surveillance footage caught videos of the fight. Video shows Briones-Blandon reaching into his backpack, drawing a knife, and stabbing Cartegena in the back, Hayden’s office said. Chelsea police questioned and arrested Briones-Blandon after he returned to the scene to recover a red motorcycle, according to the DA.

“This was an exceptionally violent incident that was captured on video, giving investigators valuable information to help determine what happened and who was involved. I offer my deepest sympathies to Mr. Cartegena and his family and friends,” Hayden said.
