I said a little prayer today for Patrolman Grennan and his family. He may be gone but never forgotten. He will always be a New York HERO.

Your heroism and service is honored today, the eighty-first 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 murdered in the line of duty on April 24, 2005 while serving as a Pittsburg, CA police officer.

Rest In Peace
