A young Cardinals fan ran a mile while holding a 'thin blue line' flag in honor of fallen Phoenix Police Commander Greg Carnicle . 

11-year-old Zechariah Cartledge, who lives in Florida, runs a mile for every first responder that loses their life in the line of duty. He ran more than 300 miles in 2019, and according to his Facebook page, , he has already run more than 50 miles this year.    

After every run, Zechariah sends the families of the fallen first responders a note and thin blue line flag. 

Zecariah is an Arizona Cardinals fan and made a trip to the Valley last year after the team heard about his mission. We met him then, and you can watch that story below.
