In a touching tribute caught on video, K9 officers and their handlers stood at attention during a funeral procession for a K9 named Bak.

Bak was a member of the MARTA Police Department for 8 years. He began his career in 2008 and was partnered with Officer Hemingway for his entire career. He covered major Atlanta events during his time on duty, including the Democratic National Convention in 2012 and the NFL Super Bowl in 2016.

“K9 Bak was always ready to work and could always be dependable to finish strong during a search," Sgt. Raymond Simms said. "K9 Bak was a friend, a partner, a defender of his handler and his country. Officer Hemingway was his life, his love, his leader. He was faithful and true, to the last beat of his heart.”

A full honor service was held for Bak on Wednesday. That service included a send off where K9 officers stood at attention as Bak's flag-covered coffin passed between their lines.

Bak was laid to rest in the Oak Rest Gardens in Gwinnett County, alongside more than 50 other K9 officers. Bak died due to medical complications unrelated to his work with MARTA police.
