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.
All the interesting, different, bizarre stories that make up the crimes that have happened that we have to investigate.
Interesting question, but I doubt I can be of much help. A body can do one of two things after death--decompose or desiccate. So it might turn into sludge or it might become a mummy. It might depend on temperature or pH levels (more relevant if the car was buried) to determine which way it would go. Being sealed would definitely slow the process to a crawl. I had a body in an attic once that was partially wrapped in plastic, and after three years the wrapped areas still had plenty of flesh and the unwrapped parts were down to bone.
Yes, we do it every day.
It could help if it's pulled hair, not cut, and if they were super-careful to leave no fingerprints or any other kind of possible DNA samples so that the police had no choice but to test the hairs for possible suspect DNA. It would also depend on the scene--if it's a heavily traveled bank, for instance, so there is a ton of discarded hairs, the police would hardly test them all. If they leave a tuft of hair on say, a chain-link fence used to get away, where the police couldn't help but notice it, then they'd have a better chance of making it a useful diversion.

What's the most dangerous situation you were ever in?
Correctional Officer
Were there a lot of suicides in your prison, and what's the most common way prisoners do it?
Air Traffic Controller
Have you ever ordered a pilot to abort mid-takeoff?
Someone trained in accident reconstruction might be able to do so, but not having marks on the road makes it more difficult.
There are usually levels of the job, like Tech I, Tech II etc. depending on years of experience that will come with an increase in salary. After that one can progress to supervisory role. But there aren't a lot of steps, really. For instance I have nowhere to go from my current position, and I don't care. I like what I'm doing and have zero interest in being the supervisor.
How much chemistry you need depends on what type of work you do. As long as you're not actually working in toxicology or DNA, you shouldn't need to be a great chemist as long as you can reliably work with chemicals and combine them properly (like following a recipe). And as long as you are a reliable and honest employee then the job is secure, once you get it, but I will be honest--there's a lot of competition in this field right now so getting into a position might be difficult. You should definitely have a back-up plan.
