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.
Wow, that’s a tough question! I’m not sure I could come up with ten.
That’s a good question that I’m afraid I can’t answer. I’m sure there is some way to determine the chemicals used in pepper spray. But this would be affected by a) how long does it remain on the skin before the skin absorbs it and b) most forensic chemistry labs are set up to detect illegal drugs in urine, blood or gastric contents. Identifying any kind of poison or other substance may require equipment or reference databases they don’t have.
Proving it’s the same batch of pepper spray may or may not be possible. I”m not personally involved in this kind of testing, but I can assure you it is not like television. We had a series of cases and wanted to determine the exact composition of drugs with percentages of fentanyl, heroin etc. Turned out while nearly every crime lab can determine if a drug is present, there were only one or two labs in the entire country we could find that could determine percentages, and they charged an arm and a leg.
Sorry I can’t be more help.
On the victim’s body? Most likely not because after that much time the victim would most likely be skeletal remains only, if buried and certainly if on the surface. If the body was in some kind of container, sealed, it might be completely decomposed, mummified or preserved, depending on circumstances. If the killer’s blood or semen got on some object that was with the body, it could conceivably survive if protected, but it would be very unlikely to yield a usable DNA profile.
Hope that helps!!
Best of luck to you! Other than taking all the science and laboratory courses possible, I would suggest checking out the websites of national forensic organizations to check job postings and what different agencies require. You might also decide if you’d consider moving and where. Try to get a tour of any forensic facility you can, this is a good way to meet people and to see what different jobs entail.
I hope that helps!

What's the rudest thing a driver ever said to you?Usually simple black powder will show gloveprints as well as fingerprints. The bubbly sort of pattern they make will be visible.
I'm not sure what you mean by post certified?
Usually I'm annoyed most often by people asking for things to be done immediately while ignoring a) that we are working on more cases than just theirs, b) that some processes take time, and/or c) that what their asking for isn't going to prove anything for them anyway.
As for fellow scientists, the worst offenses are a) finding typos in my reports and b) taking the last piece of cheesecake out of the communal fridge.
