Its not like they just found a statistically matching DNA sample and went "Lock him up, boys!". They found that not only does his DNA match, but he also lived in all of the areas where the crimes were committed, and the crime sprees in a particular area would change around the time that he relocated. He also had experience in the Navy and as a Police officer, which have been long suspected by investigators before this due to some of the behaviors exhibited by the killer. He also apparently has a unique biomarker in his sperm that matches the killer's DNA, futher reducing the chances of a random person matching.
