My your soul rest in peace


Ofc Collier's Family and Friends, Saying I'm sorry for your loss seems like little consolation after losing a family member and friend. Yet, you will hear from people around the world that pour out their hearts and give condolences to you just because of Sean's profession. Having said that, the outpouring is because we all know what type of person Sean had to be to put on the uniform every day. We know the stresses he incurred on himself and we know the ultimate sacrifice he made. Sean was part of your family and part of the law enforcement family. Please know that we are all here. When the time is right I hope you find someone to talk to and to help you through your loss. Law enforcement has it's faults, but we take care of each other. Please know our thoughts and prayers are with you.

My thoughts and prayers are with the Collier family. May he rest in peace.


Deepest sympathy to Officer Collier's family, the MIT community, and everyone struggling to deal with the tragic events of the past week.


The Collier family,
I had the pleasure of working with Sean at the Somerville Police Dept. I am deeply sorry for your loss,
Sean may you rest in Peace.


Our collective hearts in Boston are broken for your family and friends. As a student at a nearby college, I am so grateful that you had the bravery to perform your work as you did. Your selfless actions undoubtedly saved the lives of many and helped speed up the search for these criminals. Although I did not know you, the words that others have spoken about you tell me of your kindness, humility, and sweet soul. May you rest in peace. We will never forget you, and I will continue to pray for you and everyone who knew you. Thank you for your courage.


Permit me to convey my heartfelt sympathy and condolence to the MIT police department as well as the family of Office Collier.

So often civilians take for granted the members of the support services. This applies especially to campus police who are always there to help direct the lost, answer urgent calls, assist the injured, enforce the law, or even occasionally provide a friendly ride to someplace on campus. I have always found the MIT force to be kind, committed, enthusiastic and helpful.

As recently as last Tuesday (4/16), during a meeting in the faculty club, my colleagues and I received (mobile) telephone notice of a possible threat in E51. As is the "norm", the threat was investigated, determined to be false and the all-clear was sounded. We in the community depend on you doing your jobs efficiently and then telling us "things were handled". One gets used to being protected when the outcome is usually positive. So it is almost unimaginable that one of our own would fall in the line of duty at the hands of two bombers.

I am deeply appreciative for what you do. But I am deeply saddened that Ofc. Collier's family has had to pay such a heavy price for our protection. I cannot imagine a more noble way to end one's days than in the protection of others. But it does not remove the finality or the damage to those left behind--especially when one is so young. This will be very hard on the Collier family and the force as well as the MIT community as a whole. But we promise to remember. We promise to place even greater value on what you do on behalf of all of us who benefit in great (and little) ways by your service..

The only thing I can offer is a heartfelt thank you. Thank you for protecting us. Thank you for your commitment. Thank you to all the families who provide the support that allows you to work on our behalf. I promise to not take it for granted again.

I am truly sorry for the loss of one of our own members (Officer Collier) of the MIT community. As a community we all stand together as a family and when one of us is lost to such a tragic event it saddens the entire community weather we knew that person (Officer Collier) or not. My heart goes out to Officer Collier and his family.

Words escape me when I try to express what I want to say. You served your campus, community, state and this nation in ways that will touch us for the rest of our lives. Thank you.


My deepest condolences to the Collier family as well as friends and all those whom lives he touhed. As the daughter of a police officer I understand the sacrifices that are made and I partake in the grief that is shared by all officers and their families throughout the country. My prayers are with you and I hope you take solice in the fact that he died with honor and he will never be forgotten.


Your watch has ended but your soul has not. Brothers and sisters alike bleed true and blue for you. Your watch has ended but your soul lives on.

Dear Collier Family,
On Thursday night i was just a few mins away from where Officer Collier stood strong and stopped the gunmen. I don't know what would have happened to me and my friends had it not been for his heroic efforts.
May his soul rest in peace and god bless you all.

Sunita Arora

My wife and I were so deeply saddened to hear of the passing of Sean. We wanted to extend to the Collier family our heartfelt condolences. Our hearts and our prayers are with you .

We know that pain of loosing a loved one is difficult, especially under these circumstances. But we also know that you have the support and love of many family members and friends, and that their support and caring will help to provide solace and strength to you. In that spirit we include a poem from Hannah Senesh and words from Chaim Stern at the end of this note. The warm, good and loving memories of Sean will, with time, help soften the pain and far outlast the hurt. Always remember that you are embraced by the condolences and love of the MIT community.

Monty and Nancy Krieger

There are stars up above,

so far away we only see their light

long, long after the star itself is gone.

And so it is with people that we loved --

their memories keep shining ever brightly

though their time with us is done.

But the stars that light up the darkest night,

these are the lights that guide us.

As we live our days, these are the ways to remember.

-- Hannah Senesh

Rabbi Chaim Stern penned words:

We can't ask for lives free of problems...We can't ask God to make us and those we love immune to disease...We can't ask God to weave a magic spell around us so that bad things will happen only to other people, and never to us...But people who pray for courage, for strength to bear the unbearable, for the grace to remember what they have left instead of what they have lost, very often find their prayers answered. They discover that they have more strength, more courage than they ever knew themselves to have...O God, teach me to be strong enough to find a moment in the day when my heart is light enough to let me smile. Even in affliction I yearn for the grace of a loving spirit.

Professor Monty Krieger
