A drug deal in Brooklyn went bad last night, leaving a pair of twin brothers shot, one fatally.

Just after 11:15 p.m., NYPD officers responded to a 911 call inside 2003 Stillwell Avenue, near the corner of Avenue T in Gravesend, Brooklyn. There, they found two 26-year-old men with gunshot wounds to their torsos. The men were twin brothers, according to the Daily News.

One of the twins had multiple wounds, and was taken to Lutheran Hospital in critical condition. The second, identified by the police as Galvin Becerra, sustained one gunshot wound, and was unconscious on the scene. Becerra was taken to Coney Island Hospital, where he was pronounced dead.

The NYPD is seeking two shooters responsible for the incident, and believes that the drug deal may have involved marijuana. No arrests have been made as of this morning, and the investigation is ongoing.
