Lawmakers hear Davis, fault FBI on data sharing

WASHINGTON — Tensions over a possible breakdown in intelligence-sharing between the FBI and Massachusetts authorities erupted in public Thursday, when Boston Police Commissioner Edward F. Davis testified in Congress that federal agents had not told local officials of their 2011 investigation of Tamerlan Tsarnaev.

Davis said he was first told about the FBI’s previous interest in the Boston Marathon bombing suspect only after the FBI identified his body, following a confrontation with police in Watertown. Davis said he also­ was not advised of Tsarnaev’s 2012 travel to the Dagestan region of Russia, even though there are three Boston police detectives and one sergeant assigned to the Boston Joint Terrorism Task Force.
