  • Quotes

    • Hodges: According to Wendy, the blood on the murder weapon was from Thomas Harrit. It's all coming together.
      Catherine: Just give me the results.
      Hodges: I get it, you're a little touchy because you missed something the first time. Murder weapon, which was your whole case, but as of now, Catherine Willows, you are a rock star.
      Catherine: Am I going to be able to explain this to the jury?
      Hodges: You know, I'm available for court testimony if needed. Now, first I chemically tested the metal part of the hammer and found feric oxide, while not specific it does indicate that the hammer was exposed to the elements for a long period of time. Next, I document the growth of the tree around the hammer, using photos from the original crime scene and the photos that you took today. Quercus agrifolia or desert oak, grows about 6 to 8 inches a year, which means that your tree probably grew about 9 feet in 18 years. A bark collar grew around the hammer during that period of time, which confirms the hammer was in the tree for many years. And therefore no one can accuse you of planting it, pardon the pun. Unfortunately the scientific probably of getting a viable print or DNA is a completely separate issue. But, I'll back you.
      Catherine: Good to know.
