Reassembling scattered and mixed human bones by trace element ratios.

Trace metal ratios in human bones were examined to determine if there were ratios that were sufficiently consistent within an individual yet varying sufficiently from the bones of another individual so that bones in a mixed grave could be reassembled. The concentrations of 21 elements sampled at 54 places on 30 human bones in each of 5 skeletons indicated that the magnesium/zinc ratio was the most reliable and that the zinc/sodium, magnesium/sodium, and chromium/sodium ratios could be used as supplements to help reassemble human bones belonging to the same individual after all standard techniques had been used.

A new method for recovering latent fingerprints from skin.

The developed method for detecting fingerprints on live human skin involves first fuming the suspected area with iodine, and then placing a 35-mm clear plastic strip with a leuco crystal violet coating and a trace of water over the fumed area. A few seconds later a dark purple reproduction of the ridge pattern develops. It is a stable direct positive and can be mounted in a 35-mm slide mount for direct viewing. Readable prints may be obtained up to 1 h after impression on live human skin and two or three lifts may be obtained from the same print.

Scopolamine poisoning from homemade 'moon flower' wine.

LH, a 76-year-old Caucasian male, ingested 3 teaspoons (15 mL) of a homemade wine over a 1-h period and became ill. Approximately 1.5 h later, he was taken to the emergency room of a local hospital with symptoms of respiratory distress and weakness. The plant used in making the wine was Angel's trumpet (Datura suaveolens), which reportedly contains varying amounts of scopolamine and atropine. A sample of the wine was collected and analyzed for these two compounds by reversed-phase HPLC chromatography using 97% methanol-3% deionized water. The filtered wine contained an estimated 29 mg scopolamine/mL, which produced a total ingested dose of 435 mg. No atropine was detected. The scopolamine was confirmed by TLC. An oral dose of 50 mg of atropine sulfate in humans has been reported fatal, but there is no reported fatal dose for scopolamine. The alcohol content and 3.8 pH of the homemade wine may have increased the extraction of this compound from the plant material, and the wine fermentation process may have concentrated the original extract.
