The former Houston crime lab analyst has taken a beating in the Michael Bromwich reports, which determined that, among other things, the lab had manipulated results to help with convictions. And it seems that in the case of Raby, who was convicted in 1994 of brutally murdering a grandmother, Chu did exactly that.
Back in April, Raby's DNA challenge, which has been going on more than six years, was postponed yet again pending an outside expert's look into Chu's blood-typing work in the original trial.
Chu had found two separate blood types under the victim's fingernails, and they belonged to neither Raby nor the victim. Yet Chu simply listed the results as inconclusive.
The report came in last week. In her conclusion, Patricia P. Hamby, the outside expert, states that Chu's "inconclusive" reporting "is contrary to and not supported by the recorded laboratory test results for the left and right fingernail samples."
According to Raby's lawyer, Sarah Frazier, "She essentially said that he lied about it on the stand."
