Erin Corwin/Facebook |
The first part of Key's testimony consisted of explaining what DNA is for the jury. Key was very good at breaking down complicated scientific concepts for laypeople without degrees in biology (like me).
Key testified as to how DNA was obtained from Jon Corwin, Christopher Brandon Lee, and Erin Corwin (at her autopsy).
Here's what Key found:
- There was DNA consistent with Erin Corwin's DNA on the knob of the propane tank found in the mine shaft where her body was discovered. That DNA excluded both Jon Corwin and Christopher Lee as a match.
- Blood removed from the outside of one of the water jugs found in the mine shaft were Erin was discovered contained DNA consistent with Erin Corwin. That DNA also excluded both Jon Corwin and Christopher Lee as a match.
- Key found DNA consistent with Erin Corwin's DNA on the rebar handles of the garrote looped around Erin Corwin's neck. That DNA excluded both Jon Corwin and Christopher Lee as a match.
- The green t-shirt that was part of the torch found in the mine shaft where Erin Corwin's body was discovered contained DNA that had a one in 16 billion chance of belonging to someone OTHER that Christopher Lee. (The population of the Earth is just 7 billion.) Complicated way of saying the DNA on the shirt belonged to Christopher Lee. DNA on the shirt excluded Erin and Jon Corwin as possible contributors.
- Swabs taken from the mouth of the Sprite bottle found in the mine where Erin Corwin's body was discovered had two contributors of DNA, one male and one female. The male contributor was Christopher Lee (with a one in 20 quadrillion chance it was NOT Christopher Lee) and the female contributor was Erin Corwin (with a 1 in 1.4 quadrillion chance it was NOT Erin Corwin).
Lee said he looked up the "best way to dispose of a body." He mentioned a Google search produced results like having pigs devour the body, cannibalizing the body and grinding up the bones to dust, and burying a body then placing a dead animal on top of it.
Lee was asked when he was moving back to Alaska, and he replied July 7. One of the interrogators then replied, "Maybe we'll visit you in Alaska."
Court resumes at 2 p.m. I'll have another post this evening detailing this afternoon's events.
