Actually Krishna did die and his body was even cremated and most of his widows became sati on his pyre. I am not sure if Bhakti Texts like Bhagwad Puran has shown his death or not, but Mahabharat does record his human death at the hand of Jara who was an incarnation of Bali. Jara shot Krishna from behind in the same way Ram shot Bali and the arrow hit his ankle and wounded him fatally.
So, unlike his previous manifestations, Krishna didn't ascend to his abode directly. He died like an ordinary mortal.
Krishna was shot in the foot by Jara, who was said to have been a reborn Angad/Vali. Since Rama killed Vali while he was unseen and Angad never fulfilled his filial duty of avenging him, it was granted that in his next birth, he'd kill Rama's next incarnation. Hence, he shot Krishna's foot thinking it to be some part of a deer
But Rehan is not quite correct either. The devas took his body to Vaikuntha, where he resumed his role as Vishnu, which is why Arjun never found either his, nor Balaram's body. Therefore Arjun assumed that they were dead, and did shradhs in their names as well. The accounts of most of his wives ending their lives is conflicted - some say that they accompanied Arjun to Mathura/Indraprastha b4 dying, and some say that they all died in Dwarka itself.
