American flag will travel across the nation in honor of slain San Marcos officer

SAN MARCOS, Texas – An American flag is being sent across the nation in honor of slain San Marcos Officer Justin Putnam.

The flag will visit other police departments across the country, raising awareness and gathering support for Putnam, before returning home to San Marcos, Texas.

Ruck for the Fallen launched the flag, which will move to other police departments across the country to collect signatures, patches or coins, before returning home.

According to San Marcos Police Department, the flag’s journey can take up to a full year.

Putnam, 31, was killed in the line of duty as he and two other officers were responding to a domestic disturbance call on Saturday, April 18.

The suspect, Alfredo Perez Delacruz, had body armor and ambushed the officers as they entered the home. He was later found deceased from an apparent self-inflicted gunshot wound.

Officer Franco Steward and Officer Justin Mueller were also injured in the shooting. Both were in serious condition when they were hospitalized, but stable.
