The thrust of the linked article, as indicated by the title "A moment frozen in time: evidence of a late fifth-century massacre at Sandby borg", is that excavations "...revealed indisputable evidence of a massacre..." at the site. However, there are two photos of excavated beads (including millefiori) and another artifacts - see link below. An extensive reference list is appended, including several articles which may also be of some interest.
