An American flag is being sent on a nationwide journey in honor of fallen San Marcos Officer Justin Putnam. A suspect ambushed and killed the 31-year-old officer on Saturday, April 18th, and wounded two other officers as they responded to a domestic disturbance call. A support group called Ruck for the Fallen started the flag on its trip to police departments across the country. The flag may be on the road for a year before it returns to San Marcos.
