Substantial evidence is that which is of sufficient force and character that it will, with reasonable certainty and precision, compel a conclusion one way or the other, without resorting to speculation or conjecture. A person commits rape if he engages in sexual intercourse or deviate sexual activity with another person by forcible compulsion or who is less than fourteen years of age. Ark. Code Ann. Deviate sexual activity means any act of sexual gratification involving penetration however slight of the mouth of one person by the penis of another person. Ark. Code Ann.
Forcible compulsion means physical force or threat of physical injury to any person.
Ark. Code Ann. A person attempts to commit an offense if he purposely engages in conduct that constitutes a substantial step in a course of conduct intended toculminate in the commission of an offense. Ark. Code Ann. Appellant's words and actions constituted substantial evidence that he intended to engage in deviate sexual activity with his victim, and his unbuttoning of his own pants constituted a substantial step towards achieving that end. Viewed in the light most favorable to the State, this constitutes substantial evidence to support appellant's adjudication as a delinquent.
