Glen Dunbar had a degenerative disease which he tried to combat with cybernetics. So he kidnapped homeless people to harvest their organs and replaced them with straw. But he bio copied their bodies so that the police drones would stop searching them but he used an older bio printer and it could not print the organs to scale so that’s way he placed straw in them so the medical examiner wouldn’t see it. He used Micheal Costa as scapegoat for his crimes. His experiments worked, but the tech started to fail after 10 years, so he started kidnapping again but used the same equipment.
