People v. Loy
Facts
The prosecution's theory was that defendant entered his 12-year-old niece Monique's bedroom at night, sexually assaulted and killed her, and dumped her body in a vacant lot. At trial, the court admitted evidence that defendant had committed two prior sexual assaults involving rape, sodomy, oral copulation, and choking. The court also admitted testimony from Monique's friend that Monique had said she feared defendant because he touched her chest and grabbed her crotch, and it admitted expert entomology testimony estimating when the body had been left in the lot. Defendant challenged those evidentiary rulings and related jury instructions on appeal.
Issue
Did the trial court err by admitting defendant's prior sexual assaults under Evidence Code section 1108, by admitting the victim's out-of-court statement to her friend, by permitting expert testimony that relied on an unestablished foundational fact, and by instructing the jury with the pre-1999 version of CALJIC No. 2.50.01? If any rulings were erroneous, did they require reversal?
Rule
In a criminal case in which the defendant is accused of a sexual offense, Evidence Code section 1108 allows admission of other sexual offenses unless inadmissible under Evidence Code section 352. Under section 352, the court considers factors including nature, relevance, remoteness, certainty of commission, similarity, risk of confusion or undue prejudice, burden on the defense, and less prejudicial alternatives, with a presumption favoring admission under section 1108. A casual statement to a friend is not testimonial hearsay for Confrontation Clause purposes. Expert opinion may rest on reliable hearsay reasonably relied on in the field, but the expert may not substitute for proof of simple foundational facts that must be established by other evidence. Jury instructions must be assessed as a whole; the pre-1999 CALJIC No. 2.50.01 does not violate due process when the jury is otherwise fully instructed on proof beyond a reasonable doubt and the instruction does not reasonably permit conviction based solely on prior sexual offenses.
