http://people.bakersfield.com/home/Blog/BrothersTrial/7187 Defense attorney Michael Gardina questions criminalist Brenda Smith. DNA from Brothers matched DNA found in a glove tip found in the house under the items from Joanie Harper’s purse. She put the samples in the tube which she collected from the glove tip and added a chemical that would separate the DNA. She swabbed the back and front part of the glove tip to find DNA. She can’t tell where the DNA came from on the glove tip. She can’t tell if it came from the inside or the outside of the glove tip. Smith said there is no way to distinguish the inside of the glove tip from the outside. Smith explains degredation of DNA - they break into smaller and smaller pieces. Moisture, UV light, and head degrade DNA. The DNA can last for many years in the glove tip. She can’t tell how long the DNA was on the glove tip or any other item. Vincent Brothers was a major contributor because there was more of his genetic material than the other people who contributed their DNA to the mixture in the glove tip. There could be more than three contributors to the DNA found in the glove tip. She also can’t tell when the glove tip was severed from the rest of the glove.
