v.

STUART STAMMERS,

Defendant and Appellant.

Defendant Stuart Stammers was convicted by jury of forcible digital penetration following a sexual encounter with complaining witness Christina Doe. On appeal, defendant brings numerous challenges to the trial court’s admission of crude and demeaning material he sent to friends during the months leading up to the charged offense. We conclude much of the evidence was erroneously admitted and, combined with the prosecutor’s excessive focus on that evidence, ultimately deprived defendant of a fair trial. Because the due process violation was not harmless beyond a reasonable doubt, we will reverse the judgment.

I. BACKGROUND

A. TRIAL TESTIMONY ABOUT THE CHARGED OFFENSE At the time of trial, Doe had lived in California for 18 years after immigrating from China. She met defendant on a dating website in July 2022. Over the next month they exchanged messages frequently and met in person several times. On their third date they kissed and hugged. Doe was interested in continuing to pursue a relationship with defendant.

On one occasion, Doe visited defendant at his home. They shared a bottle of wine while defendant cooked dinner. Doe drank part of one glass and defendant finished the bottle. After dinner, they changed into bathing suits and sat in defendant’s hot tub for about an hour. Defendant was drinking beer. At some point defendant placed Doe on his lap and removed her bikini top. Doe testified that she would not have agreed to remove her top if defendant had asked her, but she did not put the top back on. According to Doe, she asked defendant, “Did I say it’s okay to take it off?” and defendant replied that he would “rather ask for forgiveness than permission.” Defendant denied making that statement. While defendant and Doe were in the hot tub, they kissed on the lips and defendant kissed Doe’s breast. Defendant also attempted to touch Doe’s vaginal area but stopped when she pushed his hand away.

Doe and defendant showered separately after leaving the hot tub. They then sat on a couch together and watched television. While on the couch, they touched one another and had consensual vaginal sex. Defendant stopped after a few minutes. Doe was “confused” when he stopped and “was questioning why.” Defendant testified that he and Doe attempted to have vaginal sex but stopped because he was unable to maintain a sufficient erection.

Defendant positioned himself behind Doe on the couch and touched her anus with his finger. After she told him to stop and pulled his hand away from her anus, he told her, “It’s okay, just relax.” Doe described what happened next: “After that it’s just all of a sudden I felt a big pressure pull me down and my face was facing the TV, then became facing down to the pillow, and a huge force on me and I couldn’t move. And there was enormous pain just came to something was in my butt. It was really, really painful and I was so scared. And first I couldn’t breathe at the beginning because my face was in the middle of pillow and I had to struggle to – to get to breathe first, and then – then trying to get him off of me.” She believed defendant’s penis was inside her anus because she did

not think the “enormous pain” she felt could have been caused by a finger. Doe struggled and screamed, but defendant continued for several minutes.

Doe eventually got away and went into the bathroom. Her anus was bleeding. (A forensic examination conducted later that night revealed tearing in Doe’s perianal area.) Doe then stood outside the bathroom, attempting to get defendant’s attention, but he did not notice her. After gathering her belongings, she approached defendant and told him she was bleeding. Doe asked defendant, “you don’t understand what no means?” She left the house and called 911 from the driveway.

Sheriff’s deputies met Doe nearby and interviewed her. The deputies then went to the house and spoke to defendant, who told them he and Doe had kissed and “touched” but did not have sex. They found bloody tissue in the toilet. Defendant gave them access to his cell phone for the purpose of reviewing and downloading security camera footage. Motion-activated cameras in defendant’s house had intermittently recorded the evening, including part of the sexual encounter on the couch, and recordings were played for the jury. The full sexual encounter was not captured; there was a 59-second gap in the recording.

B. EVIDENCE OF DEFENDANT’S CHARACTER AND ELECTRONIC COMMUNICATIONS Numerous character witnesses testified on defendant’s behalf. The trial court allowed the witnesses to provide opinion and reputation testimony concerning defendant’s truthfulness and nonviolent character. Defendant’s former wife and his thencurrent girlfriend testified that they had not known defendant to be sexually violent and did not believe he would be. His former wife described him as a positive role model for their children.

The trial court allowed the prosecutor to impeach the character witnesses using communications obtained from defendant’s cell phone. The evidence consisted of electronic images he sent to others during the 10 months leading up to the charged

offense. Some of the communications were also admitted as evidence of defendant’s intent or lack of mistake regarding consent. The admitted communications included: an image of a topless woman in a headdress, accompanied by the text “Sittin’ Juggs says have a great THANKSGIVING!!! And remember if the indians would have killed a mule instead of a turkey we’d all get a piece of ass for thanksgiving!!”; a Thanksgivingthemed cartoon image including the text “May your women and turkey both be moist, smokin’ hot, with big breasts, lying on their back ready to be eaten. Happy Thanksgiving!”; an image including the text “I’m kind of like a finger in the ass. I’m either a wonderful surprise or make everything fucking awkward and uncomfortable.”; an image of a man holding a microphone including the text “Asians at karaoke bars be like abba ree I can fry”; an image of a man including the text “When a girl seductively tells you, ‘you can stick it wherever you want’ apparently in her roommate is not one of the options.”; an image including the text “Fellas, If The relationship fails, don’t blame only her. It takes 2 people to mess up a relationship. Blame her and her mother”; an image of a female nurse attending to a male patient, accompanied by the text “Nurse: You may not feel anything from the waist down. Him: Just tits then?”; an image of a police officer asking a man, “So, when did you notice your wife was dead?” and the man responding, “The lovemaking was the same but then the dishes started to pile up…”; and an image including the text “He: You remind me of my little toe. She: Is it because I’m so cute and tiny? He: No, it’s because I will probably get drunk later and bang you on the coffee table.”

Defendant testified that he shared the images after receiving them from others.

The prosecutor also referenced several text messages in which defendant and a friend shared pictures of women. In those text messages, defendant made comments about one woman’s “great personality” and “testing” another woman out.

Also admitted was a video podcast excerpt of two women discussing anal sex.

Defendant sent the video to two women but did not send it to Doe. In the video, one

woman describes anal sex as “a challenge that I have to survive.” The other woman agrees and says, “How am I gonna like survive this one?” One woman describes anal sex as an “intense” experience that “gives you this high afterwards” for the rest of the day, and the video ends with the second woman replying, “everyone get your morning anal.”
