On the evening of April 18, a shooting happened on the campus of the Massachusetts Institute of Technology at 10:48 PM EDT. Multiple shots were fired. One police officer at the scene died after being shot multiple times. After killing the police officer, the suspects stole a silver Mercedes-Benz SUV in Cambridge. They forced the owner to use his ATM card to take out $800 in cash. They released him after the ATM reached its limit. The owner's cell phone was still in the car, allowing police to locate the suspects. Police exchanged gunfire with the two suspects in Watertown. One police officer was very badly hurt while exchanging gunfire with the suspects. "The Boston Globe" reported that the suspects were the same men that the FBI were looking for in the aftermath of the Marathon bombings. One of the suspects, 26-year old Tamerlan Tsarnaev, died of his injuries. The other suspect, 19-year old Dzhokhar Tsarnaev, was "still at large," according to law enforcement officials. On the morning of April 19, Massachusetts Governor Deval Patrick asked the city of Boston to "shelter in place." This meant that people should stay inside and not open their doors to anyone other than police officers with proper identification cards. As a result, the entire transit system of Boston, as well as taxi service, was shut down.
