Though neighboring communities have gone into lockdown as authorities search for the remaining suspect from Monday's attack on the Boston Marathon, Somerville is not considered to be under threat, according to an announcement from the city.
"State authorities do not perceive a threat to our community, and residents are not required to remain in their homes, but please use common sense and stay tuned to area news sources for updates," the announcement said.
The city is advising residents to stay home, keep doors locked, if possible, and not open the door for anyone other than identified law enforcement officials. Police in Somerville planned to conduct a controlled explosion near the apartment in the Inman Square area of Cambridge, where the suspects lived, according to a separate announcement.
Nearby Cambridge, Boston, and Watertown were all part of a "a shelter-in-place advisory" issued by state authorities. Many Somerville areas were eerily quiet Thursday. Davis Square, typically bustling at midday, had only a scattering of people outside and many businesses were closed.
Sean Collier, the 26-year-old MIT police officer who was allegedly shot to death by suspects Dzhokhar and Tamerlan Tsarnaev, was a resident of Somerville. The area near his Curtis Street apartment was blocked off by police Friday.
Collier worked in the Somerville Police Department's Information Technology Department as a civilian prior to becoming an officer at MIT in 2012
“Our hearts are broken today, as we learn about the death of one of our own, Sean Collier," Somerville Mayor Joseph Curtatone said in a statement. "...Sean was a tremendous young man, and we grieve for his family and friends in Somerville, and in our Department. Similarly, we grieve for the families and friends of all victims of this week’s acts of senseless violence, and hope that we can continue to unite in support of all affected.”
