As a mother of a police officer, I truly want to extend my sincere sympathy upon the untimely passing of your son, Sean. I know that my daughter wouldn't be happy doing anything else, despite the danger and risks of being a law enforcement officer. Your son paid the ultimate price in keeping the MIT community safe for all. I will keep you in my thoughts and prayers, and continue to have a heavy heart at the loss of your son. May God be with you during your time of loss and healing.

My thoughts and prayers go out to Officer Collier's family and friends at this time. This tragic loss is not only felt by the MIT community, but the U of T community as well. As U of T lowers its flag, may the proverbial flag be raised in Heaven in honor of this brave soul.

Dear Sean,
Everyday I walk by the site where you gave your life for us, and every day I will think of you as I walk to work and I will remind myself to live life with as much kindness, generosity, and bravery as you did.
Thank you.


My condolences to his family and friends. He will never be forgotten.

Rest in Peace! Your a true hero, and will always be remembered, and never forgotten. My condolences to the MIT community, family and friends of Officer Sean Collier.


It takes a special person to be an MIT officer. You have to know they see students in the midst of hacks and simply keep a watchful eye as they go about their hijinks. There are probably also moments they may have to stop students who are going a bit too far, and convince these incredibly bright kids that they might be making a poor choice that could affect them for a long time. And then there are the students who are at their absolute stress limits, who these officers might find doing things that could harm themselves or others. That ability to judge, moment to moment, how to handle the smartest people in the world as they strive and struggle and stumble through their young lives is a special gift. I sense from the little bit I have read of Officer Collier that he had that gift. It has been many years since I was at MIT, but we never forget our time there, to include all those seen and unseen who helped us through. My deepest sympathies to Officer Collier’s family and to the MIT community.

Lori Z ’90 & ‘91

The loss,of a brother is never easy. My sincerest sympathy. God has gained another guardian angel.
