The LAPD crime lab had just recently begun to do DNA testing. None of its technicians was all that experienced in the process. They were perfectly capable of performing the simplest test, called PCR DQ alpha. But it had to be done correctly. When contamination occurs, you get wildly erratic results. That was why I breathed a sigh of relief when I read Collin’s report: in this case, the results were perfectly consistent. Every blood drop on the trail at Bundy displayed O. J. Simpson’s genetic markers, and only his genetic markers. Bull’s-eye.
