New Study on Survivability of DNA Evidence

A new study published by the NIJ, demonstrates positive recovery of DNA for up to 10 days following intercourse. Given various circumstances that may lead to delays in reporting or testing, it’s good to know that current testing methods may still yield results even with a substantial delay.

The study can be accessed here (in .pdf format):  https://www.ncjrs.gov/pdffiles1/nij/grants/248682.pdf

Crime Scene Investigation and Fingerprinting

Interesting historic video on crime scene investigation and forensic science. I have a copy as well, that I purchased on DVD from the National Archives. The date on the original is a bit unclear, but it appears to have been made around 1960. It should be noted that some of the practices shown are no longer up to date, and that current safety precautions are not in use. It’s still interesting from a historical standpoint.

Conducting Successful Interrogations

By David Vessel, J. D.

This article originally appeared in the FBI Law Enforcement Bulletin, Oct. 1998, and appears on the internet at http://www.fbi.gov/library/leb/leb.htm.

SA Vessel

Obtaining information that an individual does not want to provide constitutes the sole purpose of an interrogation. A successful interrogation results in a guilty or involved criminal suspect’s making a confession or admitting participation in an illegal activity. However, interrogators frequently do not acquire information critical to successful case resolution. Often, guilty suspects leave the interrogation environment without making the smallest admission. Many experienced officers leave an interview or interrogation knowingly outwitted by the suspects. When these situations occur, criminals go unpunished and remain free to strike again, causing the entire community to suffer.
