Brian Cooper, 25, and Jamel Bannister, 22, are scheduled for arraignment today in Roxbury District Court on murder and firearms charges, the Suffolk County District Attorney's office reports. Both were nabbed not long after the shooting by Boston Police officers working a detail nearby. Transit Police say the shooting was not random - the pair targeted Jackson.
Transit Police shut the bus station, Mike Moura reports.
The T sent in a bus to transport 50 witnesses to Boston Police headquarters on Tremont Street for questioning. Every available detective in the city was ordered there to talk to the witnesses; officers were also brought in to take witnesses home.
In addition to murder and firearms charges, both also face charges of being armed career criminals, the District Attorney's office reports Bannister for drug and assault charges in 2009 and 2011 and Cooper for armed assault with intent to murder in 2007.
