Homicide Detective Bill Knowles and SLED agents continued questioning Crystals friends, and collecting DNA samples for analysis. Thousands of hours had been spent in the investigation and hundreds of suspects had been questioned. The investigators were still certain that the victim and killer knew each other.

On January 13, 1992, Ken Register had voluntarily given a statement to SLED agents relating his knowledge of the victims acquaintances, boyfriends and habits. Ken also told the agents of his whereabouts on the night of the homicide. In addition, he voluntarily consented to give blood, saliva, head and pubic hair samples, fingerprints and palm prints.
More than 50 samples of blood had been sent to SLED for testing. On February 15, Bill Knowles got a call from a SLED agent, informing him they had a match from one of the samples. The additional tests confirmed a perfect DNA match with semen taken from the victim. When given the suspects name, Knowles was shocked. He immediately began making plans for the arrest of Crystal Todds murderer -- Ken Register.
