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.

Is their an industry standard test to test for purification of blood on a forensic swab after a hematrace test results negative.

Asked by martin over 10 years ago

I don't understand what you mean by 'purification of blood.'

what are two challenges that you have to overcome? how do you overcome those challenges?

Asked by Ayah over 10 years ago

Having to testify in court, which is the most awful kind of public speaking ever because there are people there trying to make you look incompetent. You deal with it by practicing and preparing and training yourself not to take it personally. The other challenge is learning to communicate, in different ways with different groups. With victims and family/friends of victims, you have to be empathetic without talking to them about the investigation, because that's the detective's job. With co-workers, detectives and cops, you have to give them all the information they need or want without bruising their egos. This takes practice and focus.

why we use alleles frequence instead of single short tandem repeat when we want to match dna crime to suspect

Asked by atheer almost 10 years ago

As far as I know--and I am not a DNA expert--multiplying the frequencies of each allele tested is what gives us the astronomically high numbers of elimination of people having that same set of alleles. A SET of data points eliminates many more people than a single data point, in other words.

What are the things we should be looking for in an abusment case,what are the good evidence of the crime scene ? Semen,blood ..?

Asked by Mekos about 10 years ago

I don't know what you mean by 'abusement'. Like child abuse, or sexual abuse? Basically you look for whatever confirms or refutes the victims' story or your theory of the crime. First was the suspect at the right location at the right time for this crime to have occurred--you look at receipts, witness statements, GPS, anything that puts the relevant people in the right places. Then is there physical evidence of the alleged action occurring--bruises, blood, semen, a weapon found at the location. Then is that evidence tied to the suspect by DNA or other means?

Asked by Al Tyler about 10 years ago

I don't know too much about indented writing but I would suggest using alternative light sources like IR or UV.

I'm sure you are, since most positions are civilian positions without those kinds of restrictions.

Hi. I am interested in becoming a Forensic Scientist and I am a senior in high school. I had a few questions and was wondering if I could get your phone number or email address to ask you those questions. Thanks
