Found my Mom,s memorial badge in a drawer, found myself missing her and reflecting on her loss as a young girl. She was always so proud of her father, and rightfully so...Thank you for your sacrifice and legacy.

Watching the two services for the recently murdered officers has brought back painful memories. I never knew my Grandfather but will never forget the fear of my Daddy not coming home. How horrible it must have been for my Grandmother and the children when my Grandfather was killed. My Dad followed in his footsteps. We as a family ALWAYS lived with the fear of him not coming home. My heart is broken for the families.

Your heroism and service is honored today on the 65th anniversary of your death. Your memory lives and you continue to inspire. Thank you for your service.

My cherished son Larry Lasater was a fellow police officer who was murdered in the the line of duty on April 24, 2005 while serving as a Pittsburg, CA police officer.

Time never diminishes respect. Your memory will always be honored and revered.

I pray for solace for all that love and remember you for I know both the pain and pride are forever. Thanks to your family for sharing their devotion to you through their reflections.

Rest In Peace.

I remember holding his hat as a child and asking my father about him.I looked at it in awe because there was still some blood stains on the inside of the hat.I knew some of the story of his death and I even saw pictures of his funeral. May 2nd now holds new meaning for me and feelings only a child of a cop could feel and understand. I wish I knew him. RoseAnn O'Brien Sachs

Dearest Grandfather,
I never had the opportunity to know you...yet grandma "O'B" always reminded us as to what a great, loving & devoted husband & father you were. You loved the force & guarded many with your selflessness. Our dad, your first son, William J, walked in your shoes as he too gladly became an NYPD officer. How proud of you & him & the force our family still is...it may be a lifetime ago, but you are still in my heart.
In remembrance of your life given on 5/2/47...
Kathy, your first grandchild.

A dear friend recently lost her Law Enforcement husband. His name was added to a national fallen hero site. I became curious about my Grandfather's death.

I remember hearing stories from my dad, also an NYPD Officer, William Joseph O'Brien. I also remember vividly holding his hat (the uniform hat he was wearing the day he was killed), and wondering, though not understanding at the time, what it must have felt like to die.

I know that my grandfather was an excellent and competitive athlete. He was a gentle yet strong father figure, and his sense of public service was a shining example for those who knew him. I would have loved to have had just an hour to sit and share precious time with this wonderful man, I had never met.

I will always remember and deeply appreciate the sacrifices our Law Enforcement men and women have made. God Bless you Grandpa and Daddy..
