The man convicted of the 5 Dallas rapes is Sammie Luckas Cook, Jr. (public record). If you will read the
Court's Findings of Facts and Conclusions of Law in response to Darlie's
First Application for Post-Conviction Write of Habeas Corpus they address the rapes in the Dallas area. Begin at #652.

Basically, the mo was all wrong. This guy raped at apartments or apartment complexes. The Routier's home was some 12 miles from the closest sexual assault. Mr. Cook was black (Darlie maintained that the man she saw was white until the trial, then she couldn't be sure). Cook always robbed his victims; sexually assaulted the women with no additional bodily injury; did not harm the one child that was present during one of his rapes. Cook was also very threatening and vocal toward the women he raped.
This document also addresses the tube sock. I can't find it at the moment, but basically it said the tube sock was found in an area that would be opposite to someone fleeing the scene.
