Cyanoacrylate Deposition Onto Sebum With Pretreatment Of Amine, Isaac Baltz May 2024

Cyanoacrylate Deposition Onto Sebum With Pretreatment Of Amine, Isaac Baltz

Chemistry & Biochemistry Undergraduate Honors Theses

Super glue, or ethyl cyanoacrylate, fuming is commonly used in forensic science to develop latent fingerprints on nonporous surfaces[7]. Fingerprints are primarily made up of the oily substance secreted by sebaceous glands better known as sebum. Previously it has been shown that exposure of fingerprints to diisopropylamine dramatically increases the deposition of cyanoacrylate polymers on the fingerprints[1]. However, the heterogeneity of any series of real fingerprints made it difficult to quantitatively assess this effect. This heterogeneity includes not just the amount of sebum but the presence of unknown amounts of proteins, amino acids, and other potential nucleophiles which catalyze the …


Identification, Individualization, Uniqueness, David H. Kaye Mar 2016

Identification, Individualization, Uniqueness, David H. Kaye

David Kaye

Criminalists and many forensic scientists concerned with the identification of trace evidence have distinguished between identification and individualization, but they have not distinguished as precisely between individualization and uniqueness. This paper clarifies these terms and discusses the relationships among identification, individualization, and uniqueness in forensic-science evidence.


A Fourth Amendment Theory For Arrestee Dna And Other Biometric Databases, David H. Kaye Mar 2016

A Fourth Amendment Theory For Arrestee Dna And Other Biometric Databases, David H. Kaye

David Kaye

Routine DNA sampling following a custodial arrest process is now the norm in many jurisdictions, but is it consistent with the Fourth Amendment? The few courts that have addressed the question have disagreed on the answer, but all of them seem to agree on two points: (1) the reasonableness of the practice turns on a direct form of balancing of individual and governmental interests; and (2) individuals who are convicted — and even those who are merely arrested — have a greatly diminished expectation of privacy in their identities. This Article disputes these propositions and offers an improved framework for …

Can Fingerprints Lie?: Re-Weighing Fingerprint Evidence In Criminal Jury Trials, Tamara F. Lawson Jan 2003

Can Fingerprints Lie?: Re-Weighing Fingerprint Evidence In Criminal Jury Trials, Tamara F. Lawson

Articles

This article discusses fingerprint evidence and its use in criminal jury trials. It is commonly thought that fingerprints "never lie"; however, this article reveals the little known fact that the "science" of fingerprint identification has never been empirically tested or proven to be reliable. It further exposes the seldom-discussed issue of fingerprint misidentification and latent print examiner error. The article explains the importance of fingerprint evidence and its extensive use in all phases of the criminal justice system. Specifically, the article plays out the dramatic courtroom scenario of incriminating fingerprints being found at a crime scene and matching the accused …


Expert Testimony On Fingerprints: An Internet Exchange, Richard D. Friedman, David H. Kaye, Jennifer Mnookin, Dale Nance, Michael Saks Jan 2002

Expert Testimony On Fingerprints: An Internet Exchange, Richard D. Friedman, David H. Kaye, Jennifer Mnookin, Dale Nance, Michael Saks

Articles

In United States v. Llera Plaza, 188 F. Supp. 2d 549 (E.D. Pa. 2002), a federal district initially limited expert opinion testimony on fingerprint identifications because the government was unable to show that such identifications were sufficiently valid and reliable under Federal Rule of Evidence 702. Then, the court withdrew the opinion. This article reproduces an exchange of notes on the initial opinion submitted by five law professors.
