Episode 263 - Caitlin Rough Interview

In this episode, Eric and Glenn interview Caitlin Rough, a Masters student at the University of Western Sydney. Glenn saw Caitlin present at the IAFS conference back in November 2023. She comes onto the podcast to discuss her research project involving the interactions of latent prints (sebaceous residues) and blood. This work is near and dear to Glenn because of his previous work with Praska (see reference below). Caitlin discusses her observations with blood and a new twist of applying blood through various blood stain pattern mechanisms, such as swipes, spatter, pooling, and dripping. She observed the blood’s lipophobic reaction to the sebaceous ridge detail, which re-distributes the blood (often into the furrows of the mark). She also observed intermittent reactions of the blood with unknown components in the residue (as Glenn and Praska previously did). The guys discuss the implications of the research and next steps with Caitlin. Praska, N. and G. Langenburg. “Reactions of latent prints to exposed blood.” Forensic Science. International. 2013.
