No they don't
According to catholicism.about.com they do say that.
All of the apostles, having been caught up in clouds by the Holy Spirit, were transported to Bethlehem to be with Mary in her final days. Together, they carried her bed (again, with the aid of the Holy Spirit) to her home in Jerusalem, where, on the following Sunday, Christ appeared to her and told her not to fear. While Peter sang a hymn, the face of the mother of the Lord shone brighter than the light, and she rose up and blessed each of the apostles with her own hand, and all gave glory to God; and the Lord stretched forth His undefiled hands, and received her holy and blameless soul. . . . And Peter, and I John, and Paul, and Thomas, ran and wrapped up her precious feet for the consecration; and the twelve apostles put her precious and holy body upon a couch, and carried it.
The apostles took the couch bearing Mary's body to the Garden of Gethsemane, where they placed her body in a new tomb: And, behold, a perfume of sweet savour came forth out of the holy sepulchre of our Lady the mother of God; and for three days the voices of invisible angels were heard glorifying Christ our God, who had been born of her. And when the third day was ended, the voices were no longer heard; and from that time forth all knew that her spotless and precious body had been transferred to paradise.
And this "so Christ descended with a multitude of angels, and received the soul of His beloved mother." can be found at newadvent.org
