DNA evidence played a big part in Wednesday's testimony, with two experts from a crime lab unit in Albany on the stand. They tested blood samples from the rope found around Erin's neck and found the child's DNA mixed with another donor that they couldn't match. They also tested nail clippings, bed sheets and Erin's nightgown.

The prosecution only has a few more witnesses to call, including the medical examiner who performed the autopsy on Erin.
