D.C. police detectives arrested a 14-year-old boy Wednesday for the fatal shooting of a construction worker last month in Northeast Washington.

Officials did not identify the teen who was arrested on a charge of First-Degree Murder — Felony Murder While Armed for the killing of 34-year-old Balmore Mauricio Fuentes on Aug. 23.

Neighbors said that Fuentes had overseen the renovation of at least eight rowhouses in the Trinidad neighborhood and that afternoon he was working at another home in the 1100 block of Oates Street NE.

Police found Fuentes shot in the head about 1:45 p.m. that day. Authorities were investigating whether he was killed during a robbery attempt in the alley near the home.

Officials did not release any details about the investigation Wednesday night.
