I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
Good question. If the surface isn't disturbed and the temperature and humidity are cool and steady, I know fingerprints can last indefinitely, so I suppose skin cells would last as well.

I'm not trying to be snippy, but no, I really can't. 'Forensics' could be anything from having a PhD in genetics to working in evidence intake. Start with why you're thinking about it as a career, what it is you see yourself doing. Then try to find facilities near you that do that and ask for a tour. It's a good way to get specific answers to specific questions as well as begin to make contacts in the field.

So the victim was killed and put in a freezer, then moved to another state and put in another freezer? I have no idea how that would be figured out, unless they leave some compelling clue frozen with the victim.

You can cut off a sample of the tampon or sheet (if you don't want to cut a hole in your sheet, just take a clean cotton swab, dampen with water, and rub on the stain until some of the stain transfers...do that before you wash the sheet or it probably won't work well). Let it air-dry, if necessary, and package in a clean envelope. Then rub a clean cotton swab on the inside of your own mouth for your own standard and seal in a separate clean envelope. Don't put anything in plastic. You should be able to get those tested at a lab, such as LabCorp, though it might take some explaining since they usually do parent-child comparisons. This will cost you anywhere from $250 to $600, according to their website. Of course all that will do is tell you if the blood is yours. It won't tell you whose it is. PS if it's a tiny amount on the sheets it could also be from him--shaving nick, shin scrape, that sort of thing. We bleed a lot more than we realize.

I'm sorry but that's a very broad question. What kind of pattern and impression evidence are you talking about?
