I'm running in memory of my Grandfather, Chicago Police Officer Thomas J. Murphy. He was killed in the line of duty. Thanks to all of you that honor his memory by donating! The R2R 5K raises money for the Chicago Police Memorial Foundation to help it fulfill it's mission of providing financial assistance to those families whose loved one was killed in the line of duty or catastrophically injured. The run will be on Saturday 4 May 2013.
