Overview
- Rayquon Brown, 29, was arrested Monday and charged with murder, illegal firearm possession, being an armed career criminal, and conspiring to commit murder; he was arraigned and is being held without bail pending further court proceedings.
- The victim, 32‑year‑old Xavier Bautista, a Cambridge Department of Public Works employee, was found near Broadway and Norfolk Street with two gunshot wounds after being approached by several masked men on the morning of July 4.
- Prosecutors say investigators tied Brown to a vehicle at the scene and believe he acted as a lookout and was seen holding an object consistent with a firearm, based on witness accounts and surveillance video review.
- Police and the Middlesex district attorney say the homicide investigation remains active, with increased patrols, public appeals for tips and no additional arrests or confirmed motive announced so far.
- The killing has renewed debate over Cambridge’s recent decision to deactivate ShotSpotter, a microphone‑based gunshot detection system that police unions say might have sped discovery while city leaders cited accuracy and privacy concerns.
