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’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.

Because that's not our job. That's the detective's job. They're in charge of and responsible for the investigation.

No. I do lots of stuff detectives don’t do, like lab analysis, scene reconstruction, latent print comparison, etc. And they do tons of stuff I don’t do, like track down victims/witnesses/suspects and interview them, run criminal histories, request search warrants, and so on. So our jobs are really very different. We are there to provide the forensic support for the case, but forensic topics are only part of any case. Hope that helps!

That would depend a great deal on the circumstances. Any hair actually on the victim that does not appear to belong to the victim would likely be collected. If there was obviously a struggle, if the victim was beaten or strangled, hairs on their hands or caught in their fingers would warrant special attention or any clumps of hair nearby. If the victim's lying on a carpet that apparently hasn't been vacuumed for the past decade, then single hairs might be disregarded. If the person is outside and shot from a distance, then hairs would likely be disregarded.
I hope that helps!

Why do you post questions that need to be deleted? Most people have better things to do.

I'm sorry but I have absolutely no idea. I didn't know there was a cost. I would have guessed that their attorney could request a court order to do so from the judge and the police agency that has the print would take care of it, but I really don't know. Sorry I can't be more help.

I haven’t ever done an autopsy at all, since I’m not a pathologist. They can be done on animals, usually it’s called a necropsy and may be done by a veterinarian.
