As he signed off for the last time before retiring, an Arizona police officer was surprised at the voices speaking back to him over the the walkie-talkie system!

His three sons decided to honor their father in his last day on the job by speaking to him through the radio in his squad car.

They offered him comments of gratitude and admiration for his role as father and officer. Each speaking of how inspirational their father was to him and their family.

The video of this touching moment went viral on Twitter and rightfully so!

We wish the best for the officer during his retirement!
