Case Brief Summary & Legal Analysis
tl;dr: A defendant was charged with possessing child pornography. The court allowed the prosecution to introduce evidence of his possession of legal but similar explicit materials to prove he knowingly possessed the illegal images, applying the “doctrine of chances.”
Legal Significance: This case illustrates the application of the “doctrine of chances” under FRE 404(b), allowing evidence of similar, even legal, “other acts” to prove knowledge and rebut a defense of accident or mistake in a possession case.
Case Facts & Court Holding
Key Facts & Case Background
Jonathan Tanguay was charged with knowingly possessing child pornography found on his computer, an external hard drive, and a CD. At trial, Tanguay’s defense was that he did not place the illegal material on his devices and was unaware of its presence. The government sought to introduce other materials found on the same devices: sexually explicit stories involving male children, suggestive photographs of young-looking men, pornographic photos of an 18-year-old, and bookmarks to explicit websites. Tanguay filed a motion in limine to exclude this evidence, arguing it was impermissible character evidence under Federal Rule of Evidence (FRE) 404(b)(1). He further argued that, even if relevant for a non-propensity purpose, the evidence’s probative value was substantially outweighed by the danger of unfair prejudice under FRE 403. The government contended the evidence was admissible to prove Tanguay’s knowledge, a key element of the offense and a central issue in the case.
