 He participated in ongoing discussions with the Shroud Science Group, a group of about 100 scientists, historians, and archeologists who continue to study the Shroud of Turin.Rogers's continual study of the Shroud resulted from a 2000 study by Joseph Marino and Sue Benford, based on x-ray analysis of the sample sites, showing a probable seam from a repair attempt running diagonally through the area from which the sample was taken.These researchers conclude that the samples tested by the three labs were more or less contaminated by this repair attempt.
