The mural shows the faces of six officers who worked to evacuate people before the blast and reads "I Believe in Heroes."
The wording is a play on the famous "I Believe in Nashville" mural.
The officers are Amanda Topping, Michael Sipos, James Luellen, Brenna Hosey, James Wells and their sergeant Timothy Miller.

The bombing took place early Christmas morning. Investigators said Anthony Quinn Warner, 63, blew himself up in the blast.
Despite hundreds of tips and leads, as well as a history of investigating Warner, his motive for the explosion is not fully known.
Warner did subscribe to many conspiracy theories, and his ex-girlfriend said he had threatened suicide in the past.
