The prosecution case was largely circumstantial, because there was no evidence directly connecting Solomon with the crimes. Witness testimony connected him as an acquaintance of some of the victims. Tellingly, except in one case, all the victims were found at locations where Solomon had either lived or had worked as a handyman. Although police had a blood sample, DNA testing was in its infancy and no connection was made by means of that technology. However, a semen sample had been collected from Johnson's body and it was determined to be consistent with Solomon's blood.
