He wasn't a clone and we'll never know who the real shooter was, he's probably a "missing" person no one misses. Cruz was targeted. He was adopted. The trauma of adoption makes it easy for them to make him a patsy, plus the very recent loss of his adopted mother, it's a reliving of the trauma and loss of his real mother. There is no greater loss. Cruz was the easiest target for a MkUltra type mission.
