The man fatally shot by antiterrorism officers in Boston on Tuesday and the suspect arrested Tuesday night in Everett had conspired to kill a police officer, according to two law enforcement officials briefed on the case.
“We believe the intent was to behead a police officer,” one official said Wednesday morning. “We knew the plot had to be stopped. They were planning to take action Tuesday.”
The other official said Boston police and the FBI and the Joint Terrorism Task Force were aware of the plot because of intelligence that had been gathered, and the suspects had been under surveillance for several weeks.
