Swimsuit Boy is the only full set of remains that have not been identified. But, victim # 27 was recovered containing one or two extra bones not belonging to him. Did these bones come from another unidentified victim? Or did the extra bones come from a known victim which got accidentally mixed in with the remains of #27 by accident? I emailed Sharon Derrick back in 2011 and was told the extra bone(s) were sent to get a DNA extraction but I don't know if they were successful in doing so. I believe that there was probably another 3 - 6 victims who will never be identified as additional remains have not been located. The wikipedia article on Dean Corll does a fairly good job of addressing the possibility of additional victims.
