Newe methods used for the finding of fire causes
Přichystal, Lukáš ; Vávrová, Milada (referee) ; Osvald, Josef (advisor)
Master’s thesis deals with a determination problem of ignitable liquids from fire debris. The aim of this work is to introduce the properties of used fire accelerants and to give an overview and evaluation of the various techniques which can be conducive to the fire investigator. Determination of fire accelerants from fire debris was made by the technique of solid phase microextraction (SPME) with subsequent chemical analysis by GC/MS. Based on the chromatographic results were established the target compounds and reconstructed ion chromatograms which are typical for some kinds of flammable liquids. There were used gasoline, diesel, kerosene and technical gasoline (white spirit) as the fire accelerants. This work also deals with the influence of interfering products in fire debris analysis, including their identification and characterization. Different kinds of substrates were burned, extracted and analyzed in order to identify all the interfering products that they may release.
Offender profiling and the possibilities for its use in arson cases.
Linhartová, Barbora ; Boukalová, Hedvika (advisor) ; Gillernová, Ilona (referee)
The theme of the thesis is psychological offender profiling and the possibilities that it offers in the investigation of arson cases. First it introduces profiling as an investigation method, including its history, the sources on which it is based, what kind of information it contains and how it is created. Next it follows up the problematic issue of fires, their investigation and the classification of intentionally set fires. It also introduces some particular arsonist offender subtypes. Then it pursues the arson profiling and introduces the main profiling approaches. In the end, the author applies the acquired findings to analyze two arson cases according to the particular profiling approaches and then compares the provided leads to a possible offender.
