People v. Garcia

Supreme Court of Colorado
113 P.3d 775 (2005)


On July 11, 1999, Steve Garcia (defendant), a diagnosed diabetic, injected himself with a dose of insulin. Garcia did not eat anything after administering the insulin. Thereafter, while running errands, Johnie, Garcia’s wife, noticed that Garcia was acting strangely. Without warning, Garcia hit Johnie in the head with a hammer while they were exiting a parking lot in their van. Johnie escaped the van and began to run, but Garcia pursued her and ran her over, severely injuring her. The State of Colorado (plaintiff) charged Garcia with attempted first-degree murder, among other crimes. Prior to trial, Garcia gave notice that he would assert the affirmative defense of involuntary intoxication, contending that he was not responsible for the crime because he suffered from insulin-induced hypoglycemia at the time of the incident. Garcia proposed to call a doctor to testify that the insulin dosage, in conjunction with a lack of food, caused a hypoglycemic condition that affected Garcia’s ability to think rationally and that consequently prevented his ability to form the requisite mens rea for first-degree attempted murder. The trial court concluded that insulin-induced hypoglycemia can never constitute the affirmative defense of involuntary intoxication. While the trial court instructed the jury on the defense of insanity, the court did not provide instructions on involuntary intoxication. The jury convicted Garcia. Garcia appealed. The court of appeals held that the trial court erred in prohibiting Garcia from producing evidence to support the defense. The state petitioned the Colorado Supreme Court for certiorari. The court granted the petition.
