At about 12:08 AM on Monday, December 7, 2015, officers assigned to District A-7 (East Boston) responded to a radio call for a person requesting EMS in the area of Bremen Street. On arrival, officers went to an apartment where the 911 call had been made. The officers discovered the door had been left ajar and the apartment was unoccupied. The officers returned to the first floor of the building where they were met by a security guard who said that the resident of the apartment had just come downstairs, threatened him with a knife and then ran back upstairs. The officers returned to the apartment and immediately saw the suspect standing in the hallway holding a large kitchen knife. The officers drew their firearms, created distance and gave numerous verbal commands for the suspect to drop the knife. The suspect did not comply and instead began screaming at the officers “Kill me! Shoot me!” as he pointed the knife at them. The suspect suddenly took three steps towards the officers, stopped, and took three steps backwards, all the while pointing the knife at the officers in a threatening manner. The suspect repeated this pattern several times while continuing to yell at the officers to kill him. One of the officers took cover in an open elevator while keeping the door open to maintain a visual of the suspect. The second officer backed further down the hall, holstered his weapon and attempted to calm the armed suspect. The suspect continued to appear agitated and charged towards the officer in the hallway who again took out his firearm. With the suspect’s full attention on the officer in the hallway, he was caught by surprise as he passed the officer in the elevator who sprayed him in the face with pepper spray, causing the suspect to retreat. Officers were eventually able to convince the suspect to drop the knife and took him into custody after a brief struggle. The suspect was transported to a local hospital for medical treatment and a psychiatric evaluation.
