An alternative carrier solvent for fingermark enhancement reagents
Olszowska, Izabela; Deacon, Paul; Lindsay, Maurice; Lesniewski, Adam; Niedziolka-Jonssona, Joanna; Farrugia, Kevin J. (Article)Solstice® Performance Fluid (PF), trans-1-chloro-3,3,3-trifluoropropene, is presented as an alternative to HFE7100, methoxy-nonafluorobutane, as a carrier solvent in a number of chemical formulations used for the visualisation ... -
An Assessment of a Portable Cyanoacrylate Fuming System (LumiFume) for the Development of Latent Fingermarks
Jones, Calum; Fraser, Joanna; Deacon, Paul; Lindsay, Maurice; Carlysle-Davies, Felicity; Farrugia, Kevin J. (Article)The effectiveness and suitability of a portable cyanoacrylate fuming system (LumiFume™) with Lumicyano™ at detecting latent fingermarks was assessed. The first phase of the study compared the LumiFume™ system with traditional ... -
Chemical enhancement of soil-based marks on nonporous surfaces followed by gelatin lifting
Hammell, Louise; Deacon, Paul; Farrugia, Kevin J. (Article)This study assessed the use of processing techniques (potassium thiocyanate, 2-2-dipyridil, potassium ferrocyanide, ammonium pyrrolidinedithiocarbamate, safranin, magnetic powder) for the enhancement of soil-based marks ... -
A comparison between atmospheric/humidity and vacuum cyanoacrylate fuming of latent fingermarks
Fraser, Joanna; Friel, Laurel; Adams, Duncan; Attard-Montalto, Nicola; Deacon, Paul; Farrugia, Kevin J. (Article)A number of pseudo-operational trials were set up to compare the atmospheric/humidity and vacuum cyanoacrylate fuming processes on plastic carrier bags. The fuming processes were compared using two-step cyanoacrylate fuming ... -
The effect of cyanoacrylate fuming on subsequent protein stain enhancement of fingermarks in blood
Mutter, Nicole; Deacon, Paul; Farrugia, Kevin J. (Article)This study investigates the effect of cyanoacrylate (CA) fuming, at atmospheric and vacuum conditions, on subsequent protein stain (acid violet 17) enhancement of fingermarks in blood. Fingermark depletions in blood were ... -
The effect of mark enhancement techniques on the presumptive and confirmatory tests for blood
An investigation into the effects of physical and chemical enhancement on subsequent presumptive and confirmatory tests for human blood is presented. Human blood was deposited onto porous (white 80gsm paper and brown ... -
The effect of mark enhancement techniques on the subsequent detection of saliva
There appears to be a limited but growing body of research on the sequential analysis/treatment of multiple types of evidence. The development of an integrated forensic approach is necessary to maximise evidence recovery ... -
The effect of mark enhancement techniques on the subsequent detection of semen/spermatozoa
Deacon, Paul; Phillips, Darren; Farrugia, Kevin J.; Simmons, Rory K. (Article)Fingermarks, footwear marks, blood and semen are amongst the most commonly encountered types of evidence at crime scenes. Previous work has extensively investigated fingermark and blood enhancement techniques and a sequence ... -
Evaluation of a Hot Print System for the development of latent fingermarks on thermal paper: A pseudo-operational trial
Robb, Kiera; Deacon, Paul; Fordyce, Laura; Fennessy, Rebecca; Farrugia, Kevin J. (Article)Enhancement of latent fingermarks on thermal paper poses a number of problems when using traditional methods used for porous substrates due to blackening of the thermal layer as a result of polar solvents present within ... -
Evaluation of Lumicyano cyanoacrylate fuming process for the development of latent fingermarks on plastic carrier bags by means of a pseudo operational comparative trial
Deacon, Paul; Fraser, Joanna; Farrugia, Kevin J. (Article)There are a number of studies discussing recent developments of a one-step fluorescent cyanoacrylate process. This study is a pseudo operational trial to compare an example of a one-step fluorescent cyanoacrylate product, ... -
Further pseudo-operational trials with the Lumicyano double and co-fuming process for the detection of latent fingermarks
Hunter, Danielle; Wilson, Clarice; Hay, Stef; Sherriffs, Paul; Deacon, Paul; Farrugia, Kevin J. (Article)This study presents a number of pseudo-operational trials on plastic bags investigating the double and co-fuming process of a one-step fluorescent cyanoacrylate (LumicyanoTM) with comparisons to the two-step process with ... -
A preliminary investigation into the use of alginates for the lifting and enhancement of fingermarks in blood
Munro, Mhairi; Deacon, Paul; Farrugia, Kevin J. (Article)Recent studies have reported the use of alginate in the lifting and subsequent enhancement of footwear marks in blood. A study was set up to assess the use of such a method in the treatment of fingermarks in blood on a ... -
Pseudo-operational trials of Lumicyano solution and Lumicyano powder for the detection of latent fingermarks on various substrates
Fraser, Joanna; Calder, Nicola; Deacon, Paul; Farrugia, Kevin J. (Article)This study presents pseudo-operational trials comparing a one-step fluorescent cyanoacrylate process with a number of other enhancement techniques on a variety of substrates. This one-step process involves a product, 4% ... -
A review of one-step fluorescent cyanoacrylate techniques
Stewart, Vanessa; Deacon, Paul; Farrugia, Kevin J. (Article)A review of recent research in the use of one-step fluorescent cyanoacrylate techniques is presented. Advantages and disadvantages of such techniques in comparison to two-step processes are discussed. Further studies and ... -
Water-soaked porous evidence: a comparison of processing methods
Deacon, Paul; Simmons, Rory K.; Farrugia, Kevin J. (Article)This study compared the U.K. Home Office formulation for physical developer (PD) against Oil Red O (ORO) and a modified formulation of physical developer (MPD) that uses Tween 20 instead of Synperonic-N for enhancing ...
