Who discovered the tomb of Jesus was empty?

AnswerIn Matthew's Gospel, Mary Magdalene and the other Mary were told by the angel outside the tomb that Jesus was risen. They did not actually look to see if the tomb was really empty, but departed quickly, to tell the disciples.

In Mark's Gospel, Mary Magdalene, Mary mother of James and Salome found the stone had been moved from the sepulchre and, going in, found Jesus was gone and a young man there to tell them that Jesus was risen.

In Luke's Gospel, the women who came from Galilee, Mary Magdalene, Mary mother of James, Johanna and other women found the stone had been moved from the sepulchre and, going in, found Jesus was gone and two men in shining garments there. The two men told the women that Jesus was risen, and they went and told the disciples, who did not believe them.

In John's Gospel, Mary Magdalene found the stone moved, but it was still dark and she did not go in the sepulchre. She ran and told Peter and the 'disciple whom Jesus loved'. They ran to the tomb and it was the 'disciple whom Jesus loved' who arrived first and, looking in, saw that the tomb was empty. Peter arrived and they both went into the tomb and saw two angels.
