State v. Christman, 249 P.3d 680

Christman delivered nine and a half methadone pills to Mulder at a party; Mulder later consumed some and died from hypoxic encephalopathy with methadone, methamphetamine, and alcohol involved.
Mulder’s death occurred after the group left the dunes and Mulder showed extreme intoxication; no drugs were found in the garage the next day.
Pathologists attributed death to combined effects of substances; the state toxicology lab measured methadone at .23 mg/L but could not quantify alcohol or methamphetamine in the available sample.
Dr. Howard testified that methadone alone could be lethal at the measured level and that all three substances contributed to death; defense argued lack of quantification undermined causation.
The jury was instructed only that the defendant delivered a controlled substance and that its use resulted in death, with no proximate cause instruction given or requested.
Christman was convicted of controlled substances homicide; the court imposed a standard sentence; Christman appealed on proximate-cause and vagueness grounds.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Proximate cause requirement	Christman contends 'results in death' requires proximate cause.	Christman argues evidence does not prove proximate cause due to multiple contributing factors.	Proximate cause required; evidence sufficient to show methadone was a proximate cause, not the sole cause.
Statute vagueness as applied	As applied, statute fails to define causation clearly, risking arbitrary enforcement.	Statute provides ordinary meaning and is not unconstitutionally vague on these facts.	Statute not unconstitutionally vague as applied; causation standard satisfied by proximate-cause interpretation.
Sufficiency of the evidence	State argues the combined effects establish death caused by delivery of methadone.	Christman claims the evidence fails to prove the delivered drug caused death.	A rational jury could find beyond a reasonable doubt that methadone causally contributed to death.
