Arrest Leaves Questions About DNA Samples

With a suspect under arrest in the Louisiana serial killer case, investigators are facing questions about what they are going to do with the DNA samples collected from more than 1,000 men as part of a huge genetic dragnet.

One man is suing to have his DNA removed from police files. Legal experts said the case could help determine where the line is drawn between the interests of a criminal investigation and personal privacy. Shannon Kohler’s suit contends police lacked sufficient grounds to take his genetic information while looking for the man who killed five women in southern Louisiana.
