BAD DIRECTIONS BLAMED FOR DENVER POLICE DNA ERRORS
Comment by RICHARD EIKELENBOOM
The Denver police Laboratory made a number of mistakes in several cases over a period of 2 years.
The Denver Post states:
“The mistake happened when the crime lab’s DNA-matching machine “froze” while running a tray of 19 samples in June 2011. An analyst then called the manufacturer, which supplied a map for putting the samples back into the machine in the right sequence. More than two years passed before the crime lab realized the samples were replaced in the wrong order, after the machine froze again this past November. That time, the company gave the analyst a different map, and the samples were returned correctly. The crime lab realized the error because of the discrepancy.”
It is hard to imagine that the machine only made mistakes in 11 cases. Every case handled by this machine should be evaluated by an independent expert.
The fact that it took the lab 2 years to discover this type of error shows that the Denver police lab does not have his quality insurance program in order. If you change something to a machine one should check if it properly works after the revisions. Clearly the Denver lab did not do this otherwise they would have found the mistakes immediately.
I do understand now why the Denver police laboratory does not want us to review their DNA work and that they need the Denver DA’s headed by Mitch Morrissy to discredit me. In the Gebreyohannes case I found that in the negative DNA controls from the Denver lab, DNA was present. The Denver lab dismissed that as a minor issue in their report. I wonder if an accreditation board will see this as a minor problem. I was barred from testifying by the judge for unclear reasons.
Given their problems with the errors, the Denver police lab experts could use their time better than to look for dirt on me, which they won’t find.
