The defendant, John Cochrane, was charged with one count of possession of heroin for the purpose of trafficking.
The prosecution's case was primarily circumstantial, focusing on whether Cochrane possessed the heroin (either solely or jointly) and if the purpose of possession was trafficking.
The court applied legal principles regarding the presumption of innocence, burden of proof, proof of possession (including constructive and joint possession), and the assessment of circumstantial evidence.
The court found that while Cochrane had legal control over the apartment where the drugs were found, the evidence did not rule out the reasonable possibility that a co-occupant, Ms. Petersen, was in sole possession of the heroin.
As the prosecution failed to prove possession beyond a reasonable doubt, the defendant was found not guilty.
