During the late afternoon, police were called to quell a disturbance at a motel where the management had reported some disorderly conduct and apparent drug use. Outside the motel, the police observed Henry Egad standing by a tree.

About eighteen inches from Egad’s feet, the police discovered a matchbox on the ground. Their examination revealed that the matchbox contained a substance that later proved to be PCP, an illegal drug. Police placed Egad under arrest and charged him with possession of a controlled substance. Based on these facts alone, do you think the prosecutor can establish that Egad was in possession of the PCP?
