The abuse of new psychoactive substances (NPS) has been dramatically increasing all around the world since the late 2000s. The availability of hundreds of NPS in the past decade is challenging for both public health and global drug policies. A 39-year-old woman, known as a multidrug addict, was murdered by her partner by ligature strangulation. A comprehensive toxicological screening by gas chromatography and ultra-high performance liquid chromatography with tandem mass spectrometry revealed the simultaneous presence of ethanol (1.37 g/L), diazepam (157 ng/mL) and nordiazepam (204 ng/mL), cocaine (25 ng/mL) and benzoylecgonine (544 ng/mL), and (3-methoxy-(1-(1-phenylcyclohexyl)piperidine) or 3-MeO-PCP, a dissociative hallucinogen anesthetic drug. Concentrations of 3-MeO-PCP were 63, 64, and 94 ng/mL in femoral blood, bile, and urine, respectively. Hair tested also positive for 3-MeO-PCP on 3 × 2-cm segments at 731, 893, and 846 pg/mg, indicating long-term abuse of the drug. This seems to be the first ever reported hair concentrations. Major impairment of the victim, including visual hallucinations and alteration of behavior, was attributed to the mixture of all the drugs, with a major contribution of 3-MeO-PCP. The toxicological findings were compared to the few reports available in the medical literature.
Ricochet of a bullet in the spinal canal is well known by neurosurgeons but relatively not a common event in usual medico-legal autopsy practice. This article presents a homicide case of a penetrating gunshot injury of the lumbar spine through the T12-L1 intervertebral foramen with active movement of the projectile within the spinal canal to the L5-S1 level. This case illustrates a bullet intradural and intramedullary active movement because of a ricochet of the body of T12 with active redirection of the path. In the current literature, different types of migration in caudal or cranial direction, intradural, or intramedullary are reported. If spontaneous migration of T10 to S1 seems to be more frequent, some authors reported a C1 to S2 migration. Such migration could be asymptomatic or induce neurological impairment. The medico-legal consequences of these migrations within the spinal canal are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
