| Research Abstract |
We studied the analysis of pyrolysis products, or smoke components, from the blood of charred bodies. The analysis method included cryogenic-focusing gas chromatography-mass spectrometry following solid-phase micro-extraction of the volatile compounds from the headspace of a blood sample vial. Using this method, pyrolysis products such as phenylacetylene, styrene, indene, and naphthalene were detected from the blood of charred bodies that had accompanying heat wounds. The smoke components generated from a fire event being found in a charred body's blood could serve as evidence of the charred body having been alive at the start of the fire.
