His name was Emad. He was an environment activist and served environment for free in many years.He was living in Karaj, Iran.4 months ago he passed away because of a heart attack. Once his mother goes to cemetery to pray for Emad, sees some dogs are around his grave. She gets pretty shocked but these dogs are stray dogs and have been fed by Emad for many years.The manager of the cemetery says we noticed some stray dogs walk on cemetery but at first we did not pay attention but now we know they come here in memory of Emad.
