On August 12, three shootings in Cambridge, Roxbury, and Mattapan claimed the lives of five and injured three others. Now, police have charged a man in one of those murders.

Rosslin Altidor, 26, of Medford, was arraigned on Monday in Cambridge District Court, according to Middlesex District Attorney’s office. Police have charged Altidor with the murder of Rasaun Nichols, who was shot near Kendall Square in Cambridge around 8:41 p.m. on August 12.

“We are very grateful to members of the community who offered information following this murder,’’ Middlesex District Attorney Marian Ryan said in the release. “Good results can occur when people come forward with information they believe may be relevant.’’


Nichols, 31, was sitting in the passenger seat of a vehicle parked on Windsor Street in Cambridge when he was shot.

Altidor is being held without bail. He is due back in court on Friday, September 18.
