摘要：We reported an unusual homicidal case in which a 40-year-old woman was deceived into drinking a cup of milk that had 72 tablets of estazolam (2mg/tablet) dissolved in, and then being injected heroin aqueous solution on the right deltoid region by the criminal. At autopsy, pinpoint pupils and a new injection site on the right deltoid region were found. The pathologic pictures showed multiple patchy hemorrhages and considerable amounts of foreign amorphous substance with yellow appearance at the injection site. Some double refracting crystals with the forms of Maltese cross, acicular, rhomb or irregular were found by polarizing microscope, which may result from the diluent in heroin such as starch. Toxicological qualitative analysis by gas chromatography mass spectrometry (GC-MS) demonstrated the presence of benzodiazepine and morphine in blood and urine, and heroin in the injector left at scene. Quantitative analysis was also performed by liquid chromatography-tandem mass spectrometry (LC-MS/MS), providing the data on distribution of 6-monoacetylmorphine, morphine and estazolam in the woman's body. And the cause of death was determined to polydrug heroin-related deaths due to the combined poisoning of heroin and estazolam. It taught a lesson that the determination of other drugs, particularly central nervous system depressants in heroin poisoning were quite important in forensic expertise.
