9:10 AM PT -- Dekalb County Police say Archie was shot by his brother, Alexander Krause, at a Chevron gas station on March 25. He died at a nearby hospital on April 3. Cops say Krause was arrested for murder and is in Dekalb County Jail.
Fans have been paying respect to Archie after his passing, including NFL pro Robert Griffin III, who calls his hit song "the greatest Game Day anthem ever." There's locker room video of high school football players singing "We Ready" as inspiration.
The song was so popular, the NFL even used it in an ad.
Archie clearly touched a nerve, because social media is filling up with tributes.
