This touching photo, taken by photographer Jonathan Palmer, has been circulating online and it's easy to see why.
If you don't know the story behind it... just over a week ago, a K-9 police officer in Kentucky - 33 year old Jason Ellis - was killed in a suspected ambush.
During Ellis' funeral, his canine partner, Figo, seemed to say goodbye by placing his paw on the closed casket.
Figo had worked with Ellis to find drugs and illegal substances, and the two had quite a bond. He's now been retired and given to Ellis' widow, Amy, and his two sons, ages 6 and 7.
Ellis was shot on May 25 around 3 am on an exit ramp off a highway, not far from his home. Police say he had stopped his car, turned on his emergency lights, and got out to clear some tree limbs off the road.
According to courier-journal.com, "Investigators believe the suspect laid tree limbs on the exit ramp, then lay in wait on a hill above the ramp."
After Ellis got out of his car, he was shot with a shotgun. He was wearing his bulletproof vest and his handgun was still in its holster, police said.
The police cruiser he was driving didn't have a camera and police don't have any witnesses. A reward fund in the case has surpassed $100,000.
