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.
That depends entirely on the circumstances. If a sample of anything--blood, saliva, semen--is properly dried and kept in relatively dry conditions at a steady low temperature, or even frozen, it can last for decades. If the temperature and humidity vary greatly, then the sample could break down. If it's stored in plastic or airtight when wet it could rot and decompose.

They didn’t have forensics degrees when I went to school, so learned all the forensic tasks were on the job or continuing education courses. But the science background helps with understanding lab procedures, preparing reagents, and of course explaining what’s going on during the various processes.

I have a bachelor’s degree in biology from Cleveland State University. I didn’t have a minor.

I can't think of any one in particular that was the most 'complicated'--many were difficult and complicated for different reasons. Forensics is only part of the whole investigation, so things really get much more complicated for the detectives who not only have to absorb the information we're giving them but deal with victims, witnesses, suspects, documentation, records, warrants and prosecutors. I worked one where the victim had been taken to three different places before the body was dumped and burned, so there were indoor scenes, outdoor scenes, the suspect's house to deal with. Right now we're dealing with one that spans 30 years, so trying to find reports and piece together who did what and when and what, if anything, still remains to be done. And we had one earlier this year that had inexplicable behavior by about 9 different people over three days and all to cover up an accidental death. Hope that helps.

Every group of people looks for reasons to feel superior to any other group of people. It's (a not very attractive part of) human nature. But in my experience interagency rivalries have been super mild. It's more a trope of fiction than reality.

They used to do that in serology, taking threads soaked in the blood and putting them in tiny pools of blood type reagents. I don’t know exactly what the reagents were, sorry, that had never been part of my duties. But if you research old serological techniques you should find it.
Best of luck!

I’m sorry but I’ve never worked in toxicology. Sorry I couldn’t help!
