Forensic Scientist

Are there any famous cases in history that involved thin layer chromatography (TLC) that you are aware of? Or any interesting facts many would not know?

Asked by Mike about 5 years ago

I”m sorry but I”ve never used thin layer chromatography. If I had, it most likely would have been to distinguish extracted fiber dyes. As far as I know it’s the only way to determine if natural fibers likely had the same source.

What level math do you actually need and use?

Asked by Elizabeth G. over 5 years ago

It depends on what you want to do. I've always used only basic addition, division etc., for calculating reagents. Accident reconstruction would probably require a bit more and maybe DNA analysis, but I don't really know. Best of luck!

Have you ever did something bad, mean, or inappropriate to a dead body? What is your standard of morals and ethics?

Asked by Dolby almost 6 years ago

Quite the contrary, I find myself apologizing to them if I bump into their gurney. They’re dead. How could I not feel sorry for them?Both my department and the various forensic organizations of which I am a member have published codes of ethics to which I have always adhered.

Have you ever almost got fired before?

Asked by Mike over 5 years ago

Not that I know of.

How long does saliva DNA stay on an object? In other words, for how long the DNA is detectable?

Asked by Aj about 5 years ago

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.

Haha what if some of your old co workers see your post LAMO that’s too funny

Asked by Mike almost 6 years ago

Biggest pet peeve out of co workers? I also heard working at police and sherif departments your lunch is always stolen is this true?

Asked by Mike almost 6 years ago

That's never happened to me at the police department, but then there's only my forensic unit with access to our refrigerator so it's not a problem. But it used to happen in the lunch room at the coroner's office all the time! I injected candy with hot sauce once. That stopped it for about a week.
