UPDATE: BPD Officers Arrest Murder Suspect in Connection to Death Investigation in area of Orleans & Marginal Sts in E. Boston


Less than 24 hours after a fatal shooting incident in East Boston, the suspect responsible for the shooting is behind bars. Earlier today, BPD Homicide Detectives and members of the BPD Fugitive Apprehension Unit arrested Thorus O’Brien, 18, of Brockton and charged him with Murder. O’Brien is expected to be arraigned in East Boston District Court tomorrow, Tuesday, December 12, 2017.

Said Commissioner William Evans: “I want to commend my officers and detectives for their outstanding and ongoing commitment to keeping people safe and the fast-moving investigation that preceded the swift arrest of the suspect wanted in connection to this case. Thanks to their hard work, a dangerous individual was taken into police custody less than 24 hours after the incident. Without a doubt, an arrest like this makes our city a safer place and, hopefully, sends a loud, clear message that gun violence will not be tolerated in our city and anyone who thinks otherwise will be dealt with swiftly and severely.”
