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.
The perpetrator could be imitating a scene from the movie “Wedding Crashers” in which they put Visine in a man’s drink to give him diarrhea and vomiting. However Google tells me that’s not what it actually does, it can cause drowsiness and can be dangerous. So the motivation depends on whether the perpetrator knew what the actual effects would be or not.
As far as detecting it, it’s apparently in the imidazole family which includes histidines, so perhaps a chemical lab could detect it or some compenents of it. That would utilize thin layer chromatography and I don’t know how many labs actually do that any more—but I truly have no idea where or how or if a lab could test for it since I don’t have much of a background in chemistry, sorry!
Hope that helps.

In my personal experience, I have only testified to bloodstain pattern analysis once, and it didn’t really tell anything significant about the case because there was blood everywhere, and the fingerprints in blood weighed more than the patterns.

Like any job it gets easier the more you are accustomed and practiced in what you’re doing. I have no idea what kind of IQ you need, and it depends on what you want to do. If you want to analyze DNA you may need a PhD in genetics. But to work crime scene you need only be conscientious, reliable, observant, and willing to learn. Best of luck!

That's an awfully broad question. What do you think are the physical and chemical properties? Blood has hemoglobin. Hair grows out of your head. Footprints are impressions in the dirt. I'm pretty sure you could write a good answer to this question yourself.

Being on call and having to leave dinner or get up in the middle of the night to go to a crime scene. And having to schedule vacations and events around whether I can get someone else to cover my call for me.

I used to analyze dried paint with an FTIR, which I believe would detect lead, but as to what would be better I really don’t know. Sorry I can’t be more help.
