A 69-year-old Salem man accused of attempting to kill his ailing wife has been found not guilty by reason of insanity.

Charles Wood was arrested in January after he called 911 to report he had given his wife an overdose of insulin in an attempt to kill her and end her suffering. His wife suffers from Alzheimer’s disease and is in poor health.

Wood was charged with attempted murder, a Class X felony, and aggravated battery of a victim over the age of 60, a Class 2 felony.

Wood was examined earlier by an expert to determine if he was sane at the time of the alleged offense. The examination was completed and submitted to the court. It reportedly found that Wood was not criminally responsible for the crimes, and was not guilty by reason of insanity.

Judge Mark Stedelin ruled in Tuesday’s bench trial that evidence showed the prosecution had proven it’s case that Wood was guilty of attempted murder in that he gave his wife an overdose of insulin. Stedelin also found that Wood was sleep deprived, and despondent from watching his wife suffer without relief.

The judge ordered Wood to be evaluated by the Department of Human Services and for a treatment plan to be developed. The case is due back in Marion County court on July 17, for a status hearing on that plan.
