BOSTON, July 16, 2014—The Dorchester man charged with gunning down 25-year-old Shannon Richardson earlier this year is expected be arraigned in Superior Court next week, Suffolk County District Attorney Daniel F. Conley announced today.

The Suffolk County Grand Jury returned indictments on July 9 charging PETER CARVALHO (D.O.B. 8/11/88) with first-degree murder, unlawful possession of a firearm, and unlawful possession of ammunition. 

Carvalho was arrested May 21, the day Richardson’s murder, and has been held without bail since his Roxbury Municipal Court.  Last week’s indictments move the case from the district court to Suffolk Superior Court, where the case will be adjudicated.  Carvalho is expected to be arraigned July 21.

According to prosecutors, Richardson – a friend of Carvalho – was shot multiple times as he walked on Dudley Street on the day of May 21 and collapsed in a nearby store.  He later died of his injuries at Boston Medical Center.

Two Boston Police officers patrolling the area saw and recognized Carvalho running in the area of the shooting while clutching his waistband, which they recognized from their training as a characteristic of an armed gunman.  Officers began to pursue Carvalho, who ran straight into the store where Richardson lay dying, prosecutors said.

Assistant District Attorney Tara Burdman led the grand jury proceedings that resulted in last week’s indictments.  Arraignment will take place July 21 in the Magistrate’s Session of Suffolk Superior Court.
