An alleged poisoning with methanol and formaldehyde

It was alleged that a defendant added an unspecified amount of undyed formalin solution, containing formaldehyde and methanol, to the victim's bottle of ice and drinking water. The medical report indicated that except for a slight elevation of total creatine kinase, all other chemistry profiles were within normal ranges. The elevation of creatine kinase suggested muscle injury and inflammation; however, the significance of this elevation was not clear. Toxicological evaluations were made by conducting risk assessments. Based upon the medical report and risk assessments, the following conclusions were made: The calculated exposure doses of methanol and formaldehyde were too low to cause appreciable adverse effects; however, formaldehyde may have irritated the gastrointestinal tract causing smooth muscle and mucosal inflammation. The doses of methanol and formaldehyde were too low to cause death. The exposure scenario (a single oral exposure to formaldehyde) would not likely increase the cancer risk in the victim. The risk assessments provided resulted in a reduction in charge from attempted murder to felony.
