Patrolman Martin J. O'Brien:
It is so sad that the names of John Dillinger and Baby Face Nelson are so known. It is your name Patrolman Martin J. O'Brien that should be known. You are a hero and a man to be looked up to. May you rest in peace and thank you and your family for the ultimate sacrifice. WE are a better people today because you walked among us yesterday.

Time may have passed but you are not forgotten. I believe as long as someone remembers you or speaks your name, you are still with us.
Thank you for your heroism.
God Bless

To fully appreciate the heroes of the present, we must recognize our heroes of the past. . Your heroism and service is honored today, the 78th 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 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.

Rest In Peace.
