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.

Hi! I'm writing a mystery where the murder weapon is a maduvu, a knife with two antelope horns. I'm wondering what would distinguish the wound to make it unique to that weapon, assuming the victim was stabbed in the chest or back. Thanks!

Asked by katrosswriter@gmail.com almost 10 years ago

Wow, you'd really have to ask a pathologist. But I would assume a stab wound with a horn would look different than one from a knife, more round and uniform. You might also have a sliver of horn break off in the wound. The round wound in the flesh or bone might make a doctor think it came from a bullet at first, but with no bullet found then they might think icepick or something horn-shaped. Best of luck!

What are some skills and abilities a person would need to be successful in this type of work?

You have to have good attention to detail, can work under stress and unpredictable circumstances, be patient and cautious. 

Greetings. I am writing a murder mystery in which the victim died from a blow to the head. The killer then loaded the body into the back of an SUV, where it lay for perhaps up to 6 hours. Then the killer dumped the body in a location where he was hoping to frame someone.

First question. Several hours after death, could there still be enough blood at the location of the head wound to leave blood evidence at the dump location? Would there be any way for the forensic experts to determine that that blood landed where it did several hours after its owner had died?

Another scenario. What if the killer, in the process of dumping the body, tried to make it look like the victim died in that location by bashing his head, in the vicinity of the wound, on the corner of a dumpster? What kind of evidence might such a maneuver leave?

I hope this question makes sense... Thank you. :)

Asked by CrankyBeach over 9 years ago

First question: My guess is (simply based on experience) is there would still be sticky blood at the head wound enough to smear on stuff, perhaps. It wouldn't be spurting or perhaps even dripping at that point because it should have begun to coagulate. Provided it didn't dry entirely, so the body would need to be in a place that's neither too dry nor too hot and certainly not both. Cool and humid would keep it from drying. The killer might bash the head but there could be a lack of blood spatter or flowing/pooling blood from the wound, since the blood won't be flowing as it would be if the person had still been alive. Also the problem with moving the body is lividity where the blood pools at the lower spots of the body due to gravity (like on the back if the person is lying supine. After several hours it should be fairly noticeable and then if you move the body, the lividity pattern doesn't quite match the position.

Hope that helps!

Been reading through these with great interest Lisa, I love forensic science! if criminals had time and the area was very small what is the best way for criminals to either erase or cover up there DNA? Thanks:)

Asked by tommy k over 9 years ago

They could try not to leave it in the first place--wear gloves and a hat, and don't cut yourself on the window you broke to gain entry. And wear a mask since you never know who has cameras where in this day and age!

Hi Ms.Black,I was wondering if you had any advice for a high school junior hoping to get into forensic science?I've been researching colleges and forensic programs in California(where I live) but I hope you can help me understand the process better.

Most agencies do not have huge staffs like on TV, and people tend to stay in the field. Thanks to the TV shows there is a universe more competition than I faced. On the other hand thanks to the current emphasis on forensics, agencies are always expanding--the federal government will be setting mandates and providing grant money to expand labs and services Check out every level (city, county, state, federal) in your area that you can find and also private labs.  Check the websites for the International Association for Identification and the American Academy of Forensic Sciences.  

Can you work as a CSI and as a forensic scientist at the same time? What I mean is that can you collect the evidence and analyze it as well?

Asked by Alyne about 9 years ago

Yes, that's what we do at our agency, depending on the analysis required. We can process for latent prints and analyze them and also cell phones and computers. For things like DNA analysis and bullet comparison, we send that to the state lab. Every agency is different depending upon available personnel and equipment.

Thanks again! So scattering hair over a crime scene would not cover the more commonly found searched for nuclear DNA? meaning the criminals in the movie (Charles town) arn't achieving much protection at all?

Asked by lisa fan over 9 years ago

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.
