Overview
- Giovani Arroyo, 22, was arrested Thursday on charges of murder, carrying a firearm without a license and conspiracy and is awaiting arraignment in Cambridge District Court.
- The victim, 32-year-old Xavier Bautista of the Cambridge Department of Public Works, was approached by masked men in the pre-dawn hours on July 4 and was later found fatally shot near Broadway and Norfolk Street by Sennott Park.
- On July 13, police arrested Rayquon Brown on multiple charges including murder and alleged that he acted as a lookout and was tied to the white Dodge Ram pickup used as the suspects' getaway; he was ordered held without bail.
- Investigators say they have not established a motive and have found no known connection between Bautista and Brown while evidence and witness accounts point to at least one suspect carrying an object consistent with a firearm.
- The shooting prompted a months-long public debate about the city's earlier deactivation of ShotSpotter and the system was turned back on last month, a move that could affect emergency response practices and local privacy discussions as the legal case proceeds.
