The DNA experts obtain the sample & then create a profile (using her parents DNA). Laboratories confirm that the DNA is indeed a match, before using it for forensics.. I'm sure it is basic "DNA 101". They would not be so silly as to "assume" just because CM drank Dr Pepper, that the can has her DNA (and compromise the entire case), without thorough testing.

Thanks. My device wont open your link. Does it say in the link that Jonni and/or Mark gave a sample for DNA comparison? MAybe it says so right there in the link IDK. I was just wondering bc I hadn't seen Jonni talk about giving a sample and she has shared so, so many details.
Sorry for the tangent.
Also, I am pro LE but everyone is human and mistakes and oversights can be made. For example, is it procedure for a car to be touched and driven (security guard and CM's dad) before the car is processed at the scene by LE? Perhaps someone will respond with, "They didn't know a crime had been committed at that time. " But in fairness to Christina, they didn't know a crime had NOT been committed at that time either. Bad syntax, but you get my point
