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.

If a person is hung on their knees, when cut down and laid on the back with the knees/gegs still stiff and bent, can the blood still pool to the back?

Asked by TK almost 6 years ago

That’s really a question for a pathologist, but apparently lividity develops before rigor, so it shoudn’t shift much after rigor has set in. However that can vary depending on temperature and physical/medical conditions. Blood will pool following the law of gravity but if the legs were bent, restricting the blood vessels, then it might pool in the torso. Sorry I can’t be more help.

Why do police still collect so much evidence even though they already have enough to prove beyond a reasonable doubt that someone did it. Like a clear video of someone doing it but they still need DNA, white seed, and a confession. I don’t understand

Asked by Jane over 5 years ago

Because trials don't occur, especially for a homicide, for another year or two or three after the crime, when there's no longer a chance to go back and collect other evidence. Confessions can be recanted, videos are never as clear as they look on TV, and everything will be challenged during a trial. And the evidence can be twisted. I had a guy who confessed to three different people the night of the crime, and then a year later went to trial and pled not guilty.

What's the best way to highlight and uncover gloveprints left by Nitrile gloves from a surface?

Asked by Richard over 5 years ago

Usually simple black powder will show gloveprints as well as fingerprints. The bubbly sort of pattern they make will be visible.

Also, is it possible to specifically detect that the DNA is from saliva and nothing else?

Asked by AJ about 5 years ago

I don't believe so, but I haven't done DNA analysis in 20 years so I'm not the best person to ask. I know there's an amylase test for saliva, but I don't know if it's used any more. And if you have a mixture I doubt it would be possible to tell what DNA is from what bodily fluid.

Can a coroner make a arrest? People like to always make the point about a “citizens arrest” but I’m sure you know what I’m talking about.

Asked by Richard over 5 years ago

I don’t really know, but at the coroner’s office I worked at I was told that our coroner was actually the highest law enforcement officer, technically, in the county. She was the only person who could arrest the sheriff if necessary. That never became necessary though so I don’t know how it would actually work.

What is the cost to a criminal defendant to have a print run through the FBI's AFIS system? Has that cost remained the same from 1999 through the present?

Asked by MsM almost 5 years ago

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.

Since my finance passed away a month ago and there's been something eating at me now and I don't want anyone to think I'm going crazy. I found him on the floor but how can his legs bend perfectly and his knees
directly on top of each other perfectly

Asked by Shell over 5 years ago

I’m sorry for your loss. What was the cause of death?
