Brian O'Neill, a 20-year-old West Nantmeal man on trial for vehicular manslaughter and felony DUI, tested positive for marijuana, according to the West Chester Daily Local. But since THC (the herb's active component) remains in the system for up to a month after ingestion, the question is whether he was actually stoned at the time of the incident.
Daniel Bush, Brian O'Neill's Pennsylvania DUI lawyer, insists that the prosecutor's evidence must prove that the marijuana in his system at the time of the accident was actively intoxicating and impacted his ability to drive a car:
"What you will see is that this case really was just an accident, one with horrific results that has ripped apart families on both sides of the case, but nevertheless just an accident."
