Characterizing The Presence Of Edta In Blood Samples, Alexandra Wright
Master of Science in Forensic Science Directed Research Projects
Blood is often a type of evidence found at crime scenes. There has been a long history of criminal cases involving blood evidence samples that were allegedly planted at the scene by a third party. Ethylenediaminetetraacetic acid, or EDTA, is an anticoagulant that is not naturally occurring in blood samples; it chelates to ions in blood to prevent clotting. If present in a blood evidence sample, it could be indicative that the blood sample may have been planted at the crime scene to implicate a suspect. EDTA is also reported to modify clothing and exist in detergents, to allow dyes …

Before an IED is sent to a laboratory for analysis, it needs to be rendered safe if it did not already initiate. Render safe procedures (RSPs) include utilizing a percussion-actuated non-electric (PAN) disrupter or a mineral water bottle disrupter. Each disrupter utilizes explosives to render the device safe by breaking open the container or disrupting the fuzing system. However, the same explosives used in the RSP are also used by criminals in IED construction. As such, the explosives used in the RSP can cause problems with the interpretation of the results from forensic analysis of the IED fragments. Compounds of …
