Forensic Scientist

Cape Coral, FL

Female, 49

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.

I have an ultraviolet flashlight; orange goggles, & phosphate detector kit. Is this all a crime specialist would use to detect semen? The stains I’m finding are not turning purple, yet I’m sure it’s semen. Is there different method/product I can use?

Asked by PH13 about 7 years ago

It may depend on how fresh the stain is and how fresh your reagents are. Plus just becuase something fluoresces does not mean it’s semen (see answer above).

I applied for a forensic technician position and I have a online interview to do within the next five days what should I expect?

Asked by DeMario about 7 years ago

I would expect it to be like any other interview--they will ask about your education and experience. If there is any practical experience you have, such as lab analyses, fingerprinting, what programs you used, they may ask specific questions about that such as which software did you use, did you use a mass spec or an electron microscope, etc. If there's things you haven't done, you might say you're aware of the theory of, say, bullet trajectory analysis but haven't had any hands-on experience. That's perfectly okay, no one is an expert in everything. Best of luck!

I stumbled across a Forensic Program on FB. I asked them questions and the person on the other side told me that it is okay not to major in a science, but take several science courses. Should I take their word?

Asked by student about 7 years ago

Every agency will have their own requirements depending on the position and their preferences. For crime scene or to work in an evidence dept, a criminal justice major may be fine. If you can find a forensic science program that may be great. There is no one answer because it depends what positions they have at each agency.

I want to use aconite in a skin cream for the murder "weapon" in my mystery novel. Could he add enough to kill, but not right away?

Asked by Gloria about 7 years ago

I'm sorry but that's beyond my technical expertise. You need a toxicologist for that one.

Best of luck!

Hello im currently a senior high school student and i always wanted to be a forensic scientist. How do you become one? As in what course should i take ? And is medical technology a good option?

Asked by Star over 7 years ago

It all depends on where you want to work and what they require. At the coroner's office we all had at least a bachelor's degree in a natural science like biology, because there were not any forensic degrees then. If you want to be a DNA analyst you will probably need to major in genetics or biochemistry. At the police department where I work, with our very small lab, we are only required to have a high school diploma--but you get extra points in the interview process for advanced degrees so we all have at least a bachelor's.I don’t know how helpful medical technology would be because that is specifically geared toward a different profession.

What does DNA contain? Other than a persons identity? Like a fingerprint found on an object, and it is swabbed, are there bactarias found as well?

Asked by Jazmin about 7 years ago

DNA is genetic material. Substances that contain cells that contain DNA, such as blood and sweat and saliva can have many other substances as well, but a crime lab would likely only look for DNA.

I’m positive that there was a lot of sexual activity in a bedroom. Therefore, there must be evidence of semen somewhere, right? Even if the person tried to be “as clean” as possible there must be drops leftover. How do u scour room to find evidence?

Asked by PH13 about 7 years ago

Sorry for the delay, I’ve been on vacation. I guess it depends where the activity took place. If it all took place in bed and they washed the sheets, then there may not be any to find. An alternate light source can look for possible spots of semen, but the problem is many things can fluoresce, such as vaginal secretions, sweat, saliva, cleaners, certain fibers, etc.
