A driver who authorities say was racing along Highway 367 after taking psychedelic mushrooms and drinking alcohol crashed in Moline Acres on Friday, killing two people and triggering a major criminal investigation. The wreck rattled the small north St. Louis County village as investigators moved in to figure out how the deadly chain of events unfolded.
Police say driver admitted to mushrooms and alcohol
According to the St. Louis Post-Dispatch, St. Louis County police told investigators the driver admitted to taking psilocybin mushrooms and drinking alcohol before racing along Highway 367 and causing the crash that killed two people in Moline Acres. Detectives are gathering physical evidence, conducting a detailed wreck reconstruction and waiting on toxicology results as they decide whether to recommend criminal charges, the paper reports.
Psilocybin's effects and legal status
Federal authorities classify psilocybin and its metabolite psilocin as Schedule I substances, making unauthorized possession illegal, according to the DEA. Clinical reviews report that psilocybin can acutely alter perception, slow reaction time and interfere with coordination, effects that experts say can seriously undermine driving ability and situational awareness. A detailed review of psilocybin's pharmacology and short-term behavioral effects is available on PubMed Central.
Testing and prosecution hurdles
Forensic and traffic-safety officials caution that detecting psychedelics in crash investigations can be technically challenging, and crime laboratories have reported rising psilocybin submissions. Specialized testing can take days to weeks, according to state traffic-safety training materials, which can slow down charging decisions in serious or fatal crashes.
Prosecutors could pursue involuntary manslaughter or other felony counts if they conclude a driver's intoxication or reckless conduct caused the deaths. Missouri's involuntary manslaughter statute covers deaths caused recklessly or by operating a vehicle while intoxicated and acting with criminal negligence. Training materials cited by the Ohio Traffic Safety Office outline those forensic challenges, and the relevant state code is summarized on Justia.
Investigation remains active
St. Louis County police say the investigation is ongoing and that officers are working with prosecutors while they wait for lab results, according to the St. Louis Post-Dispatch. No formal charging documents had been filed at the time of that report, and authorities indicated that the toxicology findings and full wreck reconstruction will play a key role in deciding whether criminal charges are filed.
Toxicology and broader laboratory analysis will be central to determining how much, if at all, the substances contributed to the crash. Scientific literature notes significant variability in how blood and tissue levels of drugs line up with real-world impairment, so results may take time to paint a clear picture. In the coming days and weeks, prosecutors, crash investigators and the victims' families are likely to be watching closely for those results and for any charging decisions tied to the state's involuntary manslaughter laws, as described in Missouri code and legal summaries. Recent research on drug effects and driving-related performance is summarized by MDPI.
